Review the craziest racquets you own

[Hitman99]

[quote=Autodidactic player;6419692]If you want to hit with a really fun illegal racket track down a Dynaspot movable mass racket. The head is filled with fluid which moves toward the tip as you swing. The result is like the Wilson hammer rackets on steroids!

So why is it illegal?

[Larrysümmers]

cuz you cant have fluid movin around in your racket, bro

That makes no sense.

The pro kennex kinetic series has all kinds of crap .....like little sand particles move all around the racquet . So why the hell not liquid ?

Here is the exact rule:

"The frame, including the handle, and the strings, shall be free of any device which makes it possible to change materially the shape of the racket, or to change materially the weight distribution in the direction of the longitudinal axis of the racket which would alter the swing moment of inertia, or to change deliberately any physical property which may affect the performance of the racket during the playing of a point. No energy source that in any way changes or affects the playing characteristics of a racket may be built into or attached to a racket." ITF Rules of Tennis, Appendix III(c)

The whole point of the Dynaspot is to "alter the swing moment of inertia" and "affect the performance of the racket during the playing of a point." The point of the lead particles in the Pro Kennex rackets, according to the manufacturer, is to reduce vibrations and make the racket more comfortable to use. Check out this study.

So all dyanspot would have to do is say "our purpose is to reduce vibrations" and poof it's legal?

No! The fluid in the Dynaspot is free flowing; it travels all the way around the head of the racket and is designed to move toward the top of the head during your swing. In other words by design it "alter[s] the swing moment of inertia." The particles in the Pro Kennex are en-capsulized and designed not to move "in the direction of the longitudinal axis of the racket" and thus it does not "alter the swing moment of inertia." This design feature makes the Pro Kennex legal and the Dynaspot illegal.

I have a pro kennex ....in fact I'm holding one right now. Those crystals do in fact move to the top of the racquet. I'm shaking it and I can feel it. But maybe I'm wrong and it just feels that way?

From what I understand, Pro Kennex got around the rule by putting the particles in "chambers" around the head and allowing the particles to move in a legal latitudinal direction (≈1/4 inch) but not an illegal longitudinal direction (≈12 inches). So, if the chambers in your racket are still intact, what you are probably feeling is the legal latitudinal movement. I know I can hear the particles move in my Pro Kennex but it doesn't seem like they move around the head. Unfortunately, the Pro Kennex is not clear so you can't see the particles moving. The fluid chamber for the Dynaspot is clear and you can see the fluid moving.

Makes sense.

Do you think it should have been made illegal? Does it really give you that much of an advantage. ?

I looked on the bay and can't find one . Any chance you would part with yours?

For a few years I used a 125" Prince POG. The distance of the sweet spot was so far from the edge of the frame, I had severe difficulty picking up low balls -- even when using a Continental grip. It can only be worse with a wider racket and a grip that forces you to life low balls by violently brushing up on them.

What are you driving at? Do you mean the vortex 133 ?

The stringing system in the vortex and the actual design of the frame and throat are unique.

It works.

Interesting questions. Yes, I believe it should be illegal because it provides an advantage, to someone skilled enough to use it, over a traditional racket. I am, however, conflicted because the Dyanspot advantage is not nearly as significant as composite versus wood in racket design or polyester versus nylon in strings or even 100 inch heads versus 60 inch heads. My bottom line is that everyone should play by the same rules so overall I'm happy with enforceable rules - even if sometimes they don't make complete sense.

As far as selling mine, sorry; I've only got one of these. They do come up from time to time on the auction sites and I've even seen them for sale here in the classifieds. While you are searching, look for any of the Maynard Air rackets, they are loads of fun as well:

[neil1b]

I'll post my pics tonigh of my weird stuff.

[VOLLEY KING]

Does anyone have one of these????

Lacoste Equijet mid 80′s

Used by Guy Forget.

No it isn’t sun damaged! Another interesting Lacoste design which aims to change the sweet spot via altered string tensions. It has a unique Vibration system in the butt cap which carried through to the Wilson T5000 model

[Autodidactic player]

I'll match your Equijet and raise you a Polygon!

[VOLLEY KING]

Oh man!!!!!!!!


You are my new idol!!!!! I'm changing my avatar to go Autodidactic!!!!!

Sheet!!!! You have to tell us a little about that equijet......

Octagon is nice for sure ......I already have the Bosworth Fox octagon one myself.bi never actually tried it though .

So what do you think of this two sticks your holiness ? .

That's it .....I'm going to figure out how the hell to post my pics .

To me my coolest stick is the spaghetti strung.....do I actually have you beat there? Can you match that? If not I will raise you one Blackburne.....


This will be cool . Let's play crazy racquet poker ?

OK, here is a spaghetti strung T-2000:



I'll call your Blackburn:



and raise you another double string face racket the Intertennis Twin:

[VOLLEY KING]

Damn you.

Ok I'm going to get medieval on you now.

I'm getting my mad raqs and my natural racquet.

I just am downloading an iPhone app that will hopefully allow me to post pics.

Do you have those ?

[VOLLEY KING]

You are the Federer of crazy racquets.

What the hell is that "intertennis twin"?????

When did that come out??

Can you talk a little about it?
