verdict on wise tension head?

#1
looking to pick up the latest wise tension head to pair with my alpha revo. saw quite a few positive statements on these forums in the past 12 years or so regarding the Wise, but is there anything negative about this?

I've owned mine for three years and have nothing negative to say. I've had it on three different machines. One was a Revo, one was another Eagnas Revo type dropweight machine, and it's currently on a Neos 1000 where it'll likely stay.

It makes stringing faster and more accurate. What more is there to say?

As far as my switching.....
I wanted faster. I prefer the 2 point vs 6 point for speed. If I had automatic release clamps, I'd likely go back to swivel instead of glide bars since I rarely do racquetball, ATW, or anything exotic.

Former Wise user. Like @dak95_00, I have nothing negative to say. I actually bought two. When the latest iteration came out, I sold my original to @loosegroove and bought the newer improved one. I did not regret the purchase. The newer model is quieter, built solid and impressive. I sold it to the club I belong to after a couple of months (for $100 less than I paid). The reason was I upgraded my entire kit to the Mighty Sensor.

The Wise is a fantastic upgrade to a lockout machine for the reasons stated above. It is also really easy to carry to a tournament and mount on an existing lockout, as I used to do.

Should you require service, the folks at Wise are competent and friendly and it won't cost you and arm and a leg.

Yup, not much to complain about with the Wise. Very happy with my purchase from @Rabbit. It works great and makes stringer that much easier (and enjoyable), though it does not pull as fast and smoothly as a dedicated high end electronic machine. A few things to mention:

1) If you string a lot of Prince O-port frames and like to use the brake on your machine when doing the crosses, that's a no go with the Wise or you might risk damaging it.

2) It's very difficult to pull two strings at once (for example when using certain methods for starting mains or using a starting clamp as a bridge).

Those are very minor things, but just thought I'd mention. I very rarely treat myself, but I'm glad I made the exception with getting the Wise.

I thought initially it was hard to get 2 strings in there but then I figured it out. Stack the strings inside the gripper and make sure they cross/twist before the gripper because it's easier for stacking. I live my WISE and the customer service. My only criticism is the ghosting the gripper leaves that's especially visible on black strings. The adjustment screw doesn't help me in this regard and the people at WISE suggested putting thin latex over the gripper teeth, lol! Other than that I love it.

Wait, so you twist before the gripper? I found the only way was to do one twist within the gripper. The gripper is slightly V'ed, so it only gripped the bottom string for me.

Weird... I don't have any issue pulling two strings at once (no twisting of any sort needed), so I'm gonna disagree on that.

I don't feel my gripper is "V" shaped at all... seems really straight and parallel sided on mine. Maybe that's why I don't have any issues pulling 2 at once (and that I keep my gripper clean).
Perhaps you've got an older model, and maybe older models had this "V" you're describing.
Mine is a Series 11.

If you twiest your string in the gripper you will crush the string. There should not be any V in the gripper the two plates should be perfectly parallel I never had and issue with my Wise pulling two strings at a time. Those plates ride on ball bearings on the top and bottom in two grooves.

@snoflewis i don’t have any negative stories to tell you about the Wise my work great for probably 10 years. But it all depends on what your really looking for. If you’re happy with the lockout tensioner you have, save your money. What are you looking to gain with a Wise?

Well there you go, must just be the gripper on my Wise. And I don't twist the string within the gripper, the twist is actually above the gripper if that makes any sense. That way the strings change orientation of which is on top and bottom and they both get pulled. One string is being gripped by the front of the plates the other by the rear. And I only ever do it with scrap string when I come up short and need to bridge.

Anywho, I'm glad I'd mentioned it because now that clarifies things. Otherwise my gripper works great, so I won't be getting a replacement anytime soon.

Please excuse my ignorance, but what is The Mighty Sensor? Nothing meaningful comes up in Google.
Sorry, that is my homage to Al "Four Touchdowns in a Single Game" Bundy who often referred to things as "The Mighty"; i.e. The Mighty Ferguson, The Mighty Wildebeest, The Mighty Cockroach, etc.

(The Ferguson is a toilet which makes a BAAAAWOOOOSH sound when flushed):)

Does it make a HSOOOWAAAB when flushed down under LOL

EDIT: Actually the water in a toilet goes around the same way in Australia as it does in the US. Only your perspective is different because you looking at it from down under. Same thing with a disk if you spin it clockwise as you see it from the top it is counterclockwise as you look at it from below.

@loosegroove im not sure what your saying but I too just use 2 strings when I do a bridge. First I go around my Diablo with one string and into the gripper then the same with the other and the second is just above first in the gripper.
 
#17
The challenge with the Wise doesn't have anything to do with the diabolo. I've found the pulling two strings at once with the Mighty Sensor (which doesn't have a diabolo) is a non-issue. The Wise's gripper was difficult to pull two strings at once. I found it to be a challenge on both models I owned. It sounds like @loosegroove has a workable solution that I didn't with the Wise though.

I didn't have a Diablo on my Wise and I never had issues with pulling 2 strings. If you have a Diablo you want to make sure that the strings are not crossed in the Diablo or in the gripper. Some people do pull 2 strings at once on the first two strings when using the Yusuki method for starting mains.

@Irvin I realize that you didn't have the diabolo. As I clearly stated, the diabolo has nothing to do with the issues on the Wise. Your comments then on the diabolo and the Wise are a non sequitur. I had the model you did albeit with a diabolo and the latest model. Like others, I found it challenging to pull two strings at one with the Wise. I use the Yusuki method exclusively now with the Mighty Sensor and find the gripper easier to manipulate than the Wise.
 
#20
@Irvin, yeah I can get the strings lined up perfectly, but the top string slips seemingly no matter what I do. No such problems using the Gamma 8800 ELS at the club. My work around isn't perfect and is fairly cumbersome, but it gets me out of a jam when I come up a little short. I'd never think of using it as standard procedure to double pull when starting mains.

Looking mainly for constant pull. Went from a dropweight to a lockout and the change in playability seems to have dropped using same string

Good to know on point 2, I start my mains with the Yusuki method and have nearly bought a Wise several times for my Neos 1000. May hold off.
 
#25
@loosegroove, both the Wise tension heads I had (yours and the new one) presented the same challenge with regard to the gripper. Your Wise had been sent back for service by me after I'd had it for a number of years. There was nothing wrong with it, I just figured it was time to let them replace older parts. It worked flawless upon return, but the two-string dilemma persisted. Did I get two units with the same flaw? I guess it could have been...but I doubt it. Maybe you and I (and others) share a faulty technique on the Wise trying to pull two strings...
 
#26
@Rabbit. Maybe we're just inept...wouldn't be the first time for me. Could just be luck of the draw, and both heads/grippers you had were within acceptable tolerances, but the plates weren't parallel enough to allow for easy double pulling. Eh, who am I kidding, we're probably just inept :cry:

NO issues for me. I pull the first two mains (stacked in the gripper) with no issues.

Yes, I've had one slip a time or few, but just being lazy or not paying attention.
My gripper pulls two strings no problem.

@loosegroove, hold the phone! I think we may have another choice. I'm going to opt for being lazy or not paying attention (although I haven't been lazy or inattentive since purchasing the Mighty Sensor it seems!).

@struggle thanks for the lifeline.
 
#29
I wasn't insinuating you were. Sorry if it came off that way. I'm saying the only time i've one slip is
when i likely wasn't paying enough attention. It IS just barely harder than pulling a single string.

And it's entirely possible that your gripper is slightly different in some way that causes such.
 
#30
@struggle - you misunderstand, mi amigo! @loosegroove and I are eternally thankful! :)

No worries, mate. I was kidding. I loved my Wise, could do a lot on it, had trouble with a very little. My problems were all solved with the Mighty Sensor (as it is idiot proof)!

@struggle thanks for the lifeline.
Come to think of it, I often string while consuming a nice New England IPA, so I can add "drunk" to the list. Combine that with one of @struggle 's options, and my excuse can be that I'm just a lazy drunk. Phew! That's way better than being inept.

On a serious note, I always slightly pull the string(s) toward me (maybe slide the gripper slightly close with my finger even) once they are in the gripper and as i'm about to hit the bat-button.
It helps engage the gripper and is quite intuitive to me, but it might not be to everyone. Give it a shot.

Have you considered pulling each string two times as demonstrated by @Irvin in some of his videos?

I have done several comparisons on my trusty ol LO maching. String jobs using the two-pull-per-string method certainly produce a slightly stiffer string bed which seems to play more consistently for a longer period of time.

When using this method, the key to consistency is to time the second pull at the same interval for every string. I usually do the initial pull, achieve LO, release the string from the gripper, count to three, do the second pull, achieve LO, and then clamp the string.

I like the look of the Wise machine but as I only string about 3 racquets per week, the "value for money" equation doesn't stack up for me. (I'd probably have to be doing 10 racquets a week before considering such a device.)

And one thing I really love about a LO Machine. No need for electricity to run the thing.

My own experience:

When I first bought my Wise, I was using the Yukusi method to start the mains. No problems with strings slipping, however I did notice that the teeth on the gripper would leave light marks on some strings. It was particularly noticeable on black poly. I don’t think it was anything other than cosmetic, but I alleviated this by placing some thick paper / thin card in the gripper.

A few years ago, a poster on here was asking about the adjustment screw (think it may have been @sp1derman actually). To assist, I adjusted mine to the two extremes in order to post photos… but forgot to make a note about where it was initially. As luck would have it, my first guess was better than I’d ever had it, and has effectively removed the marking problem on the strings. I haven’t required the card since.

One side effect of this is that when starting the mains, I found that it didn’t always grip both strings. I stacked them as many in this thread have described, and whilst the lower string would always hold firm, the top one would sometimes slip. It’s only on certain strings, so I have scraps from one I know to be ok for the rare occasion I need to use a starting clamp as a bridge. Options available to be were: a.) readjust the gripper, b.) reintroduce the card for the initial pull, c.) use a different method of starting the mains. I opted for c. A contributing factor to this is that I lost 360 degree rotation when I introduced the Wise, and so when the first pull was at the throat of the racquet, I have to pull at a slight angle. I was never crazy about doing this with two strings, and it’s a less pronounced issue when you’re only pulling one.

General notes are that I love my Wise, and it’s far more pleasant to string with than a crank. It’s less fatiguing when doing several racquets back to back, it allows me to work with both hands on the stringbed whilst pulling tension, and I believe I end up with a more consistent job because the speed of the pull is uniform (this may say more about my cranking skills). The only downsides I can see are if you lose the 360 degree rotation - not all machine will, and you do get used to that very quickly, it’s just not ideal - and the fact that it now makes it far harder for me to justify the leap to a premium machine. There’s a little part of me that thinks I should have skipped the Wise, and made the jump to something top end so that I could also benefit from an upgrade to the mounting system and clamps.

If your Wise has a gripper with an adjustment screw on the back chances are it did not come with a Diablo. The Diablo essentially the tension on the string so it creates less pressure to hold the string. If on the other hand you do have the adj screw you can limit the travel on the gripper. Limiting the travel limits the maximum pressure on the string and if you limit it too much it slips. If the gripper has too much pressure it crushes the string creating ghosting. I took my screw out and lived with the ghosting if any. I did have some slipping on very thin strings but that’s about it. The first thing I would look for if there ever is any slipping is how clean the plates are. I took my gripper plates off a few time to clean them as best as I could but would not reccomend it.

I'm not sure how you came to this conclusion. Mine has both.
Wise first had the linear gripper with no Diablo. Many customers complained some strings would slip at the front of the gripper and get damaged and many gut strings especially broke. Stringer’s that put the Wise on a Gamma machine had some real problems with the Wise because the Gamma Machines, which have a string guide, had a lower tension arm than all other lockout machines. To alleviate the problem Wise came out with a Gamma Adapter that raised the Wise up by 2” which fixed the problem of the string slipping in the front of the gripper.

Now Wise had another problem when using the Gamma Adapter that raised the Wise gripper up to the level of the stringbed you loose 360 rotation so Wise came out with a Diablo to get the 360 rotation. Some people would use the Diablo and some would not so some method of adjusting the pressure on the still needed to be included so the adjustment screw was maintained.

For a short time Wise would give a Diablo to anyone who recently bought a Wise. Then Wise started including the Diablo with the purchase of a Wise. Some used the Gamma Adapter, some didn’t. Some used the Diablo, some didn’t. If you look at the gripper on the Wise it is mounted horizontally on the top of the Wise. On a LO machine the gripper is mounted up at an angle. Those that used the diablo had no issues, those that used the Gamma Adapter had no issues, those that did not use the Diablo or the Gamma Adapter still had issues.

Wise took the adj screw off the back of the gripper to almost force everyone to use the Diablo in order to correct the design flaw in the Wise gripper IMO. You won’t find a Wise now with the adjustment screw. It all depends on which version you have.

Just wanted to chime in. I have the latest Wise model and have not had any trouble whatsoever pulling 2 strings. I use the Diablo and make sure the strings aren't twisted inside the gripper. I always use the Yusuki method.

I don't feel my gripper is "V" shaped at all... seems really straight and parallel sided on mine. Maybe that's why I don't have any issues pulling 2 at once (and that I keep my gripper clean).
Perhaps you've got an older model, and maybe older models had this "V" you're describing.
Mine is a Series 11.
I do have the diablo installed, fyi. I guess I'm wrong with "twist" but in order for the strings to stack in gripper their orientation has to change. I don't see a "V" in my gripper at all...
 
#45
I’ve owned the current version of the Wise for about 9 months now. I installed it on a Gamms XST w/ Gamma adapter. Very happy with its performance, though losing the 360-degree rotation does take getting used to. It’s not a tension head I would recommend for high volume work, but for the home stringer or someone who strings a few racquets on the side, it’s perfect.

I use Yusuki method to start and I’ve occasionally had double pull strings slip in the gripper. My solution is to wrap the string around the diablo twice - works every time.

@emptystringer why use the Gamma Adapter if you have a Diablo?
The installation instructions for the unit state that for the most accurate pull, the gripper must be on the same level as the string bed, thus I purchased/installed the adapter. But I do see your point... I've not tried operating the unit without the adapter, but assume with the diablo it would work fine. It's a minor nit...

The greater the string bends at the frame the more tension loss you're going to have. But the string will always bend either to the side as you goes farther from a center string. It seems to me if you can keep the angle constant you will have more accurate tension.
is the 360 degree rotation lost for all types of machines? not a big deal but always nice to have
You should only use the Gamma Adapter on a Gamma machine.
