***Dunlop Aerogel 1hundred (AG100) club***

Here's a review from a different angle. I just got a Head Speed Pro, and played a set with it. It is a massive weapon that just plows through any shot where you can get the racquet moving. Can't get it moving? Just stick it out and the ball will go. Anyway, after my first match using the SP, I gave it to my hitting partner and we played a few points. I used my 100, and although the swing I needed was much different from the SP, I found its mobility and quickness provided not necessarily a compensation, but a different way of being aggressive. It is so quick through the ball, even with lead. I really liked the SP, but the 100 is also a goat.

have also experienced that the larger headsize throws up a better (higher) ball than the 4D100 when stretched wide. but if one has the presence of mind (and body) to offer "more" into the shot then the 4D100 can accommodate.
 
Behold!

I have in my hands the illustrious Biomimetic 100.
(Along with the BM 200 Lite, BM 300 Tour, and Wilson K Blade 98 ).

Holding the Biomimetic is like embracing an old friend (not that I make a habit of that). Everything about it is familiar, except for the cute dimples and matte paint job. Which looks nice by the way. (Yes, even in Aqua.)

Anyhoo, demo days are here. So I'll be reporting back. My test drive my be limited, however, due to a nagging wrist injury. But I'll discern what I can.

PICS OR GTFO :p
 
Just got myself another Bio 100 today for a very nice deal as it's the last day of Thailand Open. It was a hundred bucks along with a bag. Nice, isn't it?
 
Nice, isn't it?

"Nice" would have been you snagging an armful of them and sending them to all your friends in the U.S. (But congratulations, all jealousy aside.)

So, I had my first hit with the Aqua yesterday. It felt stiff and underpowered. I was kinda disappointed.

But I have to preface my remarks. This was my first time hitting in a few months due to a hand injury. And the string tension felt much higher than what I'm accustomed to. Good thing I believe in second chances.

I was demoing this stick with a handful of others (didn't like the 200 lite, was intrigued by the 300 Tour). So next time I'll do a direct 4D-to-BM comparison. I'd really like to restring the BM100 first. Does anyone know if the TW Demo Program still allows that?

The one thing that gives me hope is that I had a very similar experience when first trying the 4D 100. I was so dialed in to my AG100, I thought the 4D seemed a little stiff and unresponsive. But once I got comfy with it, I began to like it a little better.

More to come...

Yeah, "stiff and underpowered" was what I experienced, Damp. Much more so than my demo of the original AG100 way back when. (That one was strung with NXT 16, btw.)

This has come up several times before, but the 100 series seems string-sensitive. I also believe it's a bit user-sensitive. Based on the discussion, I think you have to get any of the 100s just the way you like them to really find that "comfort" sweet spot.

K, do you know the answer to my question about re-stringing demo frames?

K, do you know the answer to my question about re-stringing demo frames?
As I recall, most of us liked the AG100 at around 55-56-57 lbs for syns and multis. A few (a minority) liked the tension higher -- Rabbit strung his with gut at 60 or 62.

TW strung the Bio 100 demos at their usual midrange + 2, i.e. 62 lbs. Way too stiff for me! And for you, apparently.

I would call TW re restringing demos.
 
BTW, my newly acquired Bio 100 is 2.4 grams heavier than my previous one. Not quite a big deal, but the big question is WHERE is it heavier. Gotta find that out and fix my other one to match.
 
It all started when I found 2 used Revelation 200 Pro MID (90" 18x20) rackets from our local market. Strung them with Weiss Cannon Silversting 1,25 and Weiss Cannon Scorpion 1,22 @21kg. Silverstring is easier on the arm and has more spinn but Scorpion has great control but has also some bad vibrations. Played with them 2 weeks and liked the weight, manouverability and precision of the 200 MID line.

I was sold to the 90" line from Dunlop.

...Got my 4D 100 rackets 2 weeks ago. Weight difference between rackets is 1g and balance poit difference 2mm- best matching rackets I have ever bought.

Strung one with Weiss Cannon Silverstring 22kg (went higher because the more open string battern). Thought that I will also try original strings on the second racket... will not try this again.

The original grips were too comfy and made the handle feel too round so I over wrapped them more tightly and the feel is much better. So with srings, and Yonex Supergrab overgrips the specs are: 333g and balance point 32cm.

First impressions about the 4D 100 compering to 200 mid:
- softer
- more dampened feel
- less plow-through
- less kick in the second serve
- better precision
- better for angles
- little bit more spin on groundstrokes

Allmost all these things I mentioned are mostly coming from more head light balance (5mm) and from the lower mass (-5g).

Tried also lead (1,5g+1,5g) in 3&9 but I like the original balance/weight more.

The 22kg felt quite right. Now the second racket is strung with the same string but 23/22kg... will see tonight what is the difference if there is any...

With the 90" head rackets the most difficult thing for me in the start was 2HBH but this is the area where I have improved most with these rackets and my 2HBH is now better then ever (previous racket: Babolat PureStorm GT).

200 Pro MID and 100 series rackets are very nice rackets. If you have 200 and the weight, balance anf feel is right for you, then I dont recomend to switch to 100. For me the more head light balance and slightly less mass feels better and that's why I prefer 100 series. Actually I was suprised that the molds of these two series are very similar. The only difference is that the 200 is narrower from the 5-7 o'clock.

About me:
Played 2 years.
Competing in local lower league.
ITN 5.

I agree with this. I am built like Rafa. Although what, 1 inch shorter. lol

I can do wonders on serve with the 4D100. I don't particularly use the topspin serve but I can still get it up to around shoulder height. I prefer the slice spin, get that thing to curve away or into the body. Have them think outside, it curves right back into the body. Great stuff right there.

I am 5'10" btw. Being a former Cornerback, is how I got the build like Rafa. lol

string tension range should be 50 +-5 lbs...IMO.

Is it colour-coding?

Blue red green yellow correspond to 100/200, 300, 400 and 500



Hey anirut,

Did you happen to ask the Dunlop people why they switched from the lime green to the aqua? I assume that the switch is worldwide and not just limited to certain areas of the world? They must have a valid reason for making the switch since it seems most customers (at least here on TT) prefer the lime-green paintjob over the aqua one. Very strange move by Dunlop since the Bio 100 hasn't been out all that long so it's not like they needed to change the paintjob to refresh an old model or anything.

Thanks. :)
 
Since I have 2 (two) Bio 100's on hand, I've experimented on one to find my proper "spec".

After hitting the wall, and adjusting for the right spec for a while, I found that adding two overgrips without removing the plastic wrap makes it feels just right.

From my past experience, a synthetic grip plus an over grip will weight about the same as leather. Give or take about 2 grams.

So I removed the gecko grip, added two layers of 3M Nexcare Transpore first aid tape -- one layer to mimick the weight of the plastic wrap (which is 2.2 grams) and one layer to add about 2.5 grams to match the other racket (which is 2.5 grams heavier). Next I put on Gamma leather and added an over grip.

Tried it on the wall, comparing to the stock one, and, voila! Perfection! It's sooooo maneuverable and easy compared to stock, inspite of the added weight. The final weight is now at 347.2 grams at about 10-11 pts HL. There's more stability and pop. Everything seems a whole lot better. The 320+ SW makes it really pop with the added weight.

I will report more tomorrow, if it doesn't rain in BKK. Seems there's a storm comin' in hard.

Oh, BTW, with a long, smooth follow through, the Bio 100 will give you that plush feel. If you play your strokes short and half-way, it can feel pretty stiff. At least this is with the factory-strung string and tension.

This is what I'm feeling, as well, with my demo of the Aqua. Without a full stroke, you can get a somewhat boardy response. Which I haven't found to be the case with both the plusher-feeling AG and 4D versions.

Granted, some of this may be due to the string job. (I really want to see how this baby does when strung low.)

anirut, I can see why this frame might appeal to you. To me, it looks like and Aerogel but feels more like your beloved Redondo.
 
FYI, it's raining in BKK right now. And it's my usual tennis time. So, I can't provide any proper feed back on the Bio 100 until I get to play ... tomorrow ... if it doesn't rain again.
 
Which one of you gearheads out there knows how to calculate swing weight?

I'll make a math word problem out of this.

If the US BM100 has a static strung weight of 11.7oz/332g and a balance of 5pts HL and a swing weight of 323...

...then the Euro BM100 with its static strung weight of 11.6oz/330g and balance of 7pts HL must have a swing weight of _________?

Thanks.

The sw has to be lower, around 320-310 dependsing on the racquet? :S

as long as we're talking swingweight - recently added 4g to the hoop of the 4D100. curious what sw is now...anyone?

use the TW swing weight calculator. seems pretty accurate for me.

If the weight is added at 12o'clock.. you can expect ~3x that in swing weight units. So, 4grams at 12 = 12+ units.

If the weight is applied to 3 & 9... you can expect ~2x that weight in sw units.

I have not experimented with anything else... 1 thing. If the weight is added under the bumper or on the outside perimeter of the hoop... expect the swing weight to up significantly more.
 
Trouble is, CHO, you can't perform the test without the racquet in hand. And I don't have a Euro BM100.

Certainly there must be some physics brains among us who can solve this riddle.

im sure some guy in a golf forum got it covered,

but heres one possibility

no accurate but enough to satisfy the Bio100 fever.

klem - thanks. will see if it feels that way in play.

CHO - think i need to get more familiar with TW calculator...thanks.
 
Just came back from two hours of playing both my Bio 100's.

Due to the !@#$%^& factory string, I find it most appropriate to hold off my comments for later. May be next week, if it doesn't rain, I'll get them strung up with my usual setup and report more.

No, no, no, anirut. Some of us wanna hear it (errr, read it). I do, anyway. Because it sounds like you're having a similar experience to mine.

Upon first hit, I don't like the U.S. Biometric 100. But I know better than to judge a frame before it's set up the way you like it.

Right now, the Aqua feels like a plank. Underpowered. Muted response. But I'm almost certain it's the strings. And I'm guessing based on the stencil that, like yours, these are factory as well. (Or does TW stencil their demos?)

So, please, type to me...

Damp

PS - It's raining here in Santa Cruz, too. Feel better?
 
^BC?

How did the tape adhere to the bumps? Normal... or some issues there?

A bit too much weight? or 'pop'?

Always thought this Bio version would play great stock and customized... maybe lead & leather?
 
Also.. some questions for the group.

-How does the Bio100/4D100 handle net play? Does it volley as crisp as Wilson90 or have the authoritative control of the PresMid?

-Also, how does it slice? You know those running forehand slices that don't float over the net... but cut past-passing your opponent at net... and he's standing there like 'well you were stretched out wide.. and blah blah blah'...

IMO, the Bio 100 I played with (not the racket in general) felt like the MW100G with un-broken-in X-One Biphase. Felt rather stiff but muted with no bad vibes. Ultra low power that my Redondo felt like a rocket launcher in comparison. And, so far, it "seems" to be suitable for more modern strokes, which is not my normal style of play.

I would certainly attribute these rather negative comments to the strings. My Redondo was strung about two months ago with Gamma Wearguard 17 at 62 and has gone through a lot of hittings that the string skin has already begun to peel. The strings are still tighter than the factory-strung Bio100's. Now, imagine a very flexy racket, tight pattern, with old, higher-tension strings that can still launch rockets! It's certainly the strings that's causing problems.

Next week I'll string both the Bio100's with Gosen Micro 16, one @58 and another @53 and compare them.
 
The racket changes a LOT if you change teh strings (4D widh original strings was wery disappointing). I dont know, how people are demoing rackets with factory strings...

I played with Silverstrings 1.25 (my main string for about 1 year) on my 4D-s for 2 weeks now. Tried 22/22, 23/22 and 25/24. Liked the most 23/22. 22/22 had more strange vibration and 25/24 no power at serv and not so good bite. Tried yesterday Signum Pro Plasma HEXtreme 1,25 (wanted SPPP 1,23 but they did not have this in my local shop) in the same tension 23/22 . Before that I thought that the Silverstring was very hand friendly poly, but Silverstring at lower tensions is making some bad vibrations. SPPHEX felt more boardy but did not have bad vibrations and felt more hand friendly. Signum had little more power and better control. Its interesting that I like SPPHEX because I dont like profile strings usually.

Will try SPPP 1,23 next and lets see what happens.

BTW: If you wanna have some good laugh, then videotape yourself playing... we did that yesterday and... :oops::twisted:

Take care!

I can comment on the net play compared to a Wilson KBT (93"). The KBT is superior at net (for me anyway). The more dense string bed and a little less frame flex = better at net. Regarding slice, FH and BH, the KBT was awesome due to the extreme control, HOWEVER every other stroke, ESPECIALLY serves and 1HBH the 4D100 blows away the KBT. The KBT was just a little too much work for me.

The only thing thing that annoys me about the 4D100, is string movement. I know:cry::oops:, it's normal for the more open pattern, but it's worth it for all the pros this frame has to offer.

Quite a few of us had this problem. I solved it by going to a hybrid with polys in the mains (and I use 18g strings).

You can solve the problem with higher tensions too, but who wants to do that! :)
 
Because i really liked Signum Pro Hextreme I tried Signum Tornado 1,23 @ the same tension 23/22. Regular spin, very boardy (crisp) but flatten out was difficult. Power was the same as with full bed Hextreme. This is not for me.

Also tried Hextreme mains and Weiss Cannon Silvestring 1,20 crosses 23/23... strange vibrations when hitting close to the top of the frame (very strange). Power was less and control was not as good as full bed Hextreme. Ball pocketing was better. I hate the word vibration, and cut it out after 30 minits of hitting.

I really like full bed Hextreme @ 23/22 and the main thing with it is control and power.

So... string is choosen for now).

What next... i didn't liked the rounded grips... i have @ home Gecko-tac grips that i ordered with these rackets. I had in past 300Tour rackets and i somehow knew that the original grips are too thick for my liking. I installed them and understood that they weight 1g less than original ones. I also use Yonex overgrip that weights about 4-5g. From this I knew that this will not end with that and tuning must go one... i decided that I will learn from the board member who have plenty experiences wit this racket and added again 1,5g + 1,5g lead at 3/9 ... now rackets weighted 335g (with strings and overgrips) and balance point was 320mm.

This setup makes so BIG difference in stabiliti and power and does not change the manuverability much. I admit that some dialing in is needed, but you dont have to whip so much around anymore to get pace. Serve is much bigger and more consistent. Angles are still there and what I really love is that no vibration at all. With this setup I'm much more consistent.

So is this the end? No... tomorrow I string the other one also with SPHextreme and its waitin for me in this situation:

Life is good:)
 
whoa...the 4g is a bit too much (at 3&9). nice pop tho. :)

dropped lead amount at 3 &9 (didn't weigh it but might be only 2g now) and think that's enough for this player. interesting to see how it performs during match play. the 4g had a little too much pop for last match play.

To you know the specs of your racket with all extras (with overgrip, dampener etc).
If you dont know exact specs then:
1. What kind of grip you are using? Original, leather (or somethin else)?
2. To you use overgrip?
3. To you use some extra weight somewhere else than 3 and 9?

My second racket with Babolat leather (22g) and 1,5+1,5g @ 3/9 weights (stung) without overgrip and dampener 340g and balance is 31,7mm.

Will try this out tomorrow and compare to the 335g 320mm one. Lets see.

Somehow i feel that if you add to original setup just overgrip (4-5g) and lead 1+1g lead at 3 and 9 would be quite optimal setup for me. I liked the original setup without overgrip more than with overgrip: more power and more stable (more head "heavy").
 
One more thing to share: when i played last time with 1,5+1,5 in 3/9 335g setup then I saw my friends BLX Pro Tour twisting in hes hand when i had a good first serve or deep powerful almost flar offensive shot. This did not happend with original setup and with previus rackets in original setup.

I also tested my friends Tour that has Luxilon Alu Power stings with tension 24/23kg and the feel was quite bad. My friend also said thet the feel of the 100 with SPPHex is much better than hes Tour has.

So: we are in the right place.

1. gamma replacement grip
2. tournagrip overgrip
3. 3-4 grams at 12

Interesting... from where the extra weight is coming from?
Is the gamma replacement grip so heavy? Is it leather?
Is the weight 351g with dampener? What dampener?

My racket would be with leather, 3g total @ 3/9 and Supregrap overgrip (4g) 344g strung. Sampras O dampener would add to that 1,5g.

What is the balance of your racket? Something close to 310-312mm?

using a rubber band dampener so negligible weight there. suspect weight might be from replacement grip. if rough measurements are correct, balance is 311+ and 314 (have 2 racquets).
 
Alright, just came back from playing the two Bio100's.

Setup: Gosen OG Micro 16. One @55 (moded 347 gram) and one @60 (stock, 337 gram with overgrip). Both strung about one hour prior to play on the same stringing machine. On my clamp-on guitar tuner, the 55 lbs tension registered F# -1/4 and the 60 lbs registered F# +1/4.

I don't use any type of dampener on my rackets.

The very first impression:
- Gosh! They suck bad time! Hitting with a plank could be much better!

After one hour, after putting up with the bad time by just banging away, sort of aimlessly:
- Things got better as the strings were more "broken-in".

After and hour and a half:
- Tried the dampener on top at 12, just to see "what if" I have 3 grams up there. Nice, more stable, but made me very slow. Moved the dampener down to the normal zone at 6 and it's good, but "not-there-yet".

The strings have much lower tension now. Each racket must have dropped over 6 lbs of tension, using my clamp-on guitar tuner to check the change in the pitch.

After two hours and ended play:
- I like the weight of the heavier, moded racket but will cetainly need 2-3 grams total at 3 & 9 for better weight behind the ball and stability. Will have to restring with 17G @60 lbs may be a day, or at least 6-8 hours, before play. (Well, I love high tension syn gut.)

The Bio100 is a nice stick, except that, for me, I need to mod it up a bit. (Well ... ain't I'm a Wizard of Mods? ;) ) I like the way I can control the shots once the strings were broken-in. I kinda like it when it rip a flat FH. The BH, for me, was a bit unstable. A little more weight in the hoop will do a lot of good. Haven't tried serving.

Now, about the feel:
- This stick will really punish you worse than the Redondo if you hit off center. The shots will be just a dud and won't go anywhere (and could go everywhere). Off-center hits felt very "planky", not jarring and doesn't feel harmful to your arm. But you certainly won't like it. If you're a precise center-hitter, the stick will reward you with a very plush and confident feel.

Next week, if I don't have to evacuate and leave Bangkok due to the floods, I'll report more with my new setup.

That's it for now. It's almost 3 AM in Bangkok and I have to monitor the flood reports too.

Cheers!

So I'm not high? Thank God.

Sorry your first impression wasn't a great one, anirut. Hope you mod your way to a more pleasant frame.

Maybe if you tried some steel strings and played in the key of C? :)
