poly spin potential

[TheLambsheadrep]

from what ive gathered on this forum, polys lose tension fast. but do polys ever lose their spin potential, possibly because of the loss of tension (if a poly is rated to have high spin, will it keep that high spin until it breaks)?

If anything, they'll actually get more spin. When they get looser, it makes easy for them to move and snapback, generating more spin. The problem is that the string bed well also become more like a trampoline, and that extra spin might not be enough to keep the ball in when the bed just launches the ball.

Not quite. Poly dies because it loses its elasticity. This means that the strings cannot snapback, and therefore spin decreases.

so poly becomes less trampoline-like over time?

Not quite. Poly dies because it loses its elasticity. This means that the strings cannot snapback, and therefore spin decreases.

If that were the case, strings that have more elasticity, such as synthetic gut and multifilaments, would have more spin, which is not true.

No, that is the case; it's your reasoning that's not right. I didn't say elasticity = spin. The mechanical structure of polyester is such that once it becomes deformed from stress aka death, it's no longer able to return to its original shape. Hence, the only elasticity that the string had is gone. WHEN that happens, the string is no longer able to snap. The other properties of polyester relating to spin when fresh are not being discussed.

i just asked because i am not a string breaker. because of this, people suggest that I stay away from poly. but as long as the poly would keep the same amount of spin/pop, I think it would be fine. I have had Red Code in a racket for about a year (like I said, not a string breaker), but I havent noticed a loss in tension. and in fact, i think the spin potential has increased as of late, but i have done a lot of customization with lead making the racket more headlight...so that may be why

You said poly dies because it loses it's elasticity. When it loses it's elasticity, it cannot snap back into place. When it cannot snap back into place, spin is decreased. The way that's worded, one might conclude elasticity = spin.

Sorry for the confusion; no arguments here

do yourself a favour and get a fresh stringjob - your elbow and shoulder will be grateful in the long run.
