and still we buy......
if the marketing were actual truth and each new "technology" actually did increase power and control, by now we wouldn't be able to see the ball...
I disagree. It is a fine racket. Great control and amazing topspin. Not because I say it, actual pros played with it and it was declared the most playable racket of the that year's crop when it came out.
If by "added internally" you mean out of sight, inside the frame, that's probably not quite true due to the manufacturing process. Otherwise, if you mean "add on your own", I agree. Adding weight at 3-9 is not a ridiculous, false pretense such as Aeroskin, liquidmetal, fewer crosses than mains and other so called technologies. It is well known to work and back when frames were more flexible it was one way to make the hoop stable.
you know the worst thing about the aero skin technology, no one actually swings the racket strait foward, but at angles. so your always going to have lots of drag
Biomimetic, (What does it do??) Mimics the nature?
Optic Spot?? I didn't see myself hitting any better with PB 8, actually I thought it was awful.
A strip of lead weighs a gram or two. Having done CAD design of rackets I can tell you that if the PWS is hollow, it doesn't weigh more than a third of a gram on each side. However, the extra width may provide some resistance to torsion.
Not sure how D3O works, but certain materials require slow, steady pressure to deform elastically, while acting rigid under sudden impact. Think of water impact: if you jump from 1000 feet in a lake you will bounce off as if you'd hit concrete, yet if you jump from 1 foot, you will hardly feel the impact because the water molecules can only move that fast out of your way. So, while not saying that D3O does what it claims, there are materials out there that could do it.
The power angle is just a different stringing pattern. You can string your favorite racket in a diagonal pattern and see if it does anything differently. Some have tried it with a K90. Do a search. My personal take is that the extra spin people experience with the Power Angle is due more to the 16x16 stringing pattern than the diagonal aspect (close string density to 16x15 of the Steam 99s).
May I offer a different take on the power aspect? I agree with both of you and CJack that stiffness is not essential to power, when the head size and string pattern are the same. However, the oversize rackets, so popular with the older players, clearly offer significantly more power. The keyword here is OVERSIZE (longer mains and crosses, more spacing between strings). Of course because of the oversize aspect, one has to use stiffer materials to make them stable. People therefore correlated stiffness with power, when in fact it is the oversize that is critical.
some types of HEAD intelligence series have integral circuit chips in the handle. i think they are so fancy.
I met a former ATP pro (he claimed to have been in the top 300s) who swore by those rackets because they were gentle on the arm, according to him. He had at least 4 of them and was using them when coaching. They still command a good price on the used market. However, the technology may no longer be legal under ITF rules.
The 'intelligence' in head i.prestige rackets is made up of goldish paint detail. There's nothing else to it.
Still a great racket.
I recall Kennex racket with like sand shifting inside the frame so it would change balance/swingweight as you swing? that was annoying, the sound of it I mean.
the worst techs are those that hurt players and/or hurt your game.
- the ultra high stiffness gets my vote too.
what other techs hurt your game or cause injury? i don't like extended length racquets because they mess with your ability to play with different sticks (you get used to the non-standard length).
The ProKennex technology is still here and has a strong following. Ask any player with tender elbows. The purpose of the sand is to redistribute the momentum from the impact with the ball to millions of grains of sand. It is not to change balance, which it doesn't.
However, no one to my knowledge has drained the sand from the racket to see if the comfortable feel is the result of the technology or simply more arm friendly graphite layering.
While the Fisher Magnetic Speed wins the overall prize, I think Head is by far the most reliable performer in this field: Flexpoint, Microgel, Liquidmetal, Youtek, Graphene... You already know it: in 2 years the marketing dept will come up with something new, at least as insulting as the previous material/technologies, while two years ago's WONDER MATERIAL will just disappear from brochures...
Perfect timing. Almost bought a 13 APD yesterday for the hell of it, the racquet is not for me. I have one handed backhand but all that cortex, and throat design and stuff almost had me departing with 200 bills.
I think the Dunlop 4Ds play better than most sticks out there.
d3o does what it claims. Just watch this video. http://www.youtube.com/watch?v=JceDaEMIHKE
English one here http://www.youtube.com/watch?v=tKQxDoXqc_I
The d3o formula is proprietary.
From most customer feedback that technology actually works.
I think Prince's "triple threat" weighting makes sense on paper, even if it was just a paint job over a little bump.
I think all this nano technology is the real BS.
That when you hit some materials they will go harder the harder you hit is not impossible. There are many materials like that.
Cortex and flexpoints...
The intelligence chips in the i series HEAD frames really are in there. There are several pages devoted to explaining how it works in the Book on Racquet Physics written by Brody, Cross, and Lindsey that was published around the same era. It's actually a pretty simple concept, and not all that complicated when you break it down.
Having said that, feel free to keep your skepticism. Chip or no chip, the iPrestiges are widely accepted as among the very best of the long lineage. They are still great racquets either way. As a long time Prestige user, I can vouch for that as well.
Sure. There have been helmets made of that material. Question is, how much of it is in the frame and does it make a difference?
But what was the contribution of the chip?
It supposedly uses the energy during the impact, and stiffens up the throat area for more power.
BS. I used the i.Prestige Mid for half a decade, what power?
Not sure about the power, but the intelligence models of the Prestige did get very stiff when you hit hard. I hit harder than about anyone, and I could definitely feel how the racket was a brick when I did hit hard. Ruined a perfectly good series of rackets and I didn't buy another Head racket until the Microgel models - which don't have the intellifibers.
I have some K2 skis with piezo-electric fibers that are actually wired in so that when the ski flexes it illuminates a light on the top of the ski. The technologies are legit. Whether they actually make any difference in the rackets (or any difference is due to things like the graphite layup or weight and balance) is disputable.
Well, at least you can sell it on the board or trade it to someone who wants it.
Wait really a chip? I thought it was just a material stripes that generate
electricity with bending. And it will stiffen material that is reactive to electricity.
By the way, I loved the placebo effects of all these technologies.
I'm not sure, but I think the "chipped" racquets were the ix. series? Those larger 115sq+ arm killers.
oh, 'optispot' has to win this
there are some vague, flimsy possibilities that things like flexpoint and aeroskin at least do something, but optispot is just completely stupid...
oh, by all means, these are great rackets, I've stated that in my post. But unless I got one and only i.prestige that has just paint detail and not a chip - there's nothing there....
Aerogel is legit... http://www.aerogel.org/
Ever hit a golf ball that didn't have any dimples?
All of these technologies and materials are legit, with real world applications.
However, the question is just how much of this stuff is actually in the racquet? We don't know the composition/graphite mixture, for all I know, there could only be 1% of such technology in these frame. Definitely enough to put a sticker on, but how much of an impact does it have?
What's your point? Everything that moves through the air must have dimples?
From reading this thread, Aeroskin and Optispot are the winners of the bogus "technology" challenge. In my opinion calling a sparse pattern (16X15 or any for that matter) "technology" is a big joke.
I know it was supposed to use the piezoelectric effect.
My question was: did it make a difference?
optispot is just paint, and is designed to make you take your eye off the ball to look at it!
The idea of aeroskin does work on airplanes. The rackets aren't moving at high speed for hours, so the effect is probably minimal.
Head's youtek drove me crazy on my prestige IG mp. One minute it felt like a rock, the next minute it was too flimsy. I swapped it with a friend for a prince exo3 rebel team. I hope graphene works out ok..
Optispot...you know how useless it is by how it's not even hyped up at all...
Has anybody mentioned the catapult thing yet?
Those were terrible rackets.
Just tried the DunlopBio300T.
I'm not saying it works, but the racket can be swung really fast, and if I can swing faster than I do now, it would seem to help.
But I'm old, injured, and out of shape, so the racket, while it seems to be easy to swing fast, I cannot swing that fast on my serves.
Compared to Mfil, Aero, and MicroGel rackets.......
I play with a Youtek Speed Pro and a Youtek Radical Pro (love high swingweights) and I do can feel the Youtek technology work... soft with touchballs and hard on higher swing speeds.
Am I the only one?
I dunno, I had youtek Speeds once, andI often wondered if it was just the sound that was different. You know that lovely 'crack' they make when you really belt one?
I could certainly 'hear' something different, but I don't think I ever 'felt' a change in response...
When I worked at a tennis shop I asked the Head rep about that (this was during the "titanium" racquet era) and he said that basically the titanium fairy flew by and sprinkled some titanium dust on the racquets.
