General Question on Stiffness.

#1
I have been playing with Prince Syn Gut Original 16 which has a 191.5 stiffness. If I string my racket with a Volkl Cyclone 17 which has the same stiffness of 191.5, would it feel about the same? I understand that the poly will be having more spin potential but I am asking whether this should make the feel about the same? I played with a PS95 6.1 Classic. I usually string it up high in the high 60s because I like the control and crisp feeling. If I string it up with Volkl Cy

Polys will feel deader and perhaps that might make it feel "stiffer" per say. I would not recommend stringing polys in the 60s. I'd say try 55 at the highest but honestly I think you'd be fine around 48-54lbs.

Read up in TWU what the Mad Scientists do to measure stiffness. It is a static measurement to stretch the string an additional 1". What you feel when playing is something we label Dynamic Tension or String Bed Stiffness. They are not the same. DT is more of an instantaneous reading of how stiff the string bed is, not an individual string. DT is measured in Kp/cm. Don't confuse the two factoids. DT with POSG is way lower than DT of Cyclone 17 at the same ref tension. Since we play with DT, we need a lower ref tension using Cyclone.

No. DT is a function of ref tension, string bed size and # of mains and crosses. There are mechanical devices that do the estimate. There a electronic devices that est based on frequency. If you have an iOS device, Racquet Tune will est DT. The ERT/Beers 300 will also est DT based on frequency. Treat as a number because the range of comfortable and usable DTs is dependent on the individual. Some like DTs in the high 40's. Others like DT in the low to mid 30s. It is just a number, and not the Answer to Life's Meaning. [a little sarcasm there.]

I used to play PSG in the mid 60’s. I string stiffer polys in the low to mid 50’s. The polys feel stiffer and have less power, but a whole lot more spin and control.

You used Volkl Cyclone as your example, so I’ll mention this. Since you’re stringing your PSG so tight, I’m guessing you really don’t like trampolining. For me, Cyclone softens and trampolines more than most stiffer polys after a couple of times out. There are plenty of others that don’t change as much as they age.

I just got a new ps97 black. Strung it up with nrg2 16 gauge at 58 and the ball is just flying off my racquet. I don't get the control I has with it on net either.

NRG2 and X1 are two of the softer and more powerful (uncontrollable unless high tension) multis in the string universe. If you can't control your shots at 58#, it's time to find a less powerful string. There are fanatics praising the virtues of Head Velocity, which is certainly a low powered multi. Head also sells something called FXP and Rip Control, which are deader and should provide the control you need at lower tensions. I prefer Prince Premiere Control if I were to use a multi. I prefer PPC over NXT due to cost.
