Hybrid stiffness question

[Steve Williams]

It seems agreed that the playing characteristics of a hybrid setup reflect the main string but are tempered by the cross. I have a question about stiffness of the string bed as a whole with each option and the resulting shock to the arm. Would a poly/multi setup be stiffer than a multi/poly if the tensions at the same (eg 48/52 and 52/48)?

multi mains/poly crosses work way better imo...stringbed locks up more easily with multi crosses cuz once poly mains wear through outer coating of the multi, then it’s much harder for mains to move around inhibiting the snapback of poly due to friction being too high.

Multi mains with a Poly cross is initialy a wonderfully comfortable and spinney setup. Feel is way improved over reverse. But and the big but is even a very modest power hitting player will have the poly crosses saw through the mains in a matter of hours of hitting. The Poly mains multi cross can last for months for a light club player though.

Thanks for your replies. What I am asking is to do with the overall stiffness (as in tolerable/intolerable for wrist and elbow) of the stringbed. I’ve never had tennis elbow and don’t want to start. I have used multi mains and soft poly crosses. Some make my arm stiff some don’t. If I reversed the combinations that don’t feel OK (i.e., poly/multi) is my arm more likely to suffer afterwards?

Depends. If your stringer is careful and gets a consistent ref tension on the crosses, the DT will be very similar. That's why you straighten crosses, wiggle them before clamping.

If the stringer is not careful, then the crosses will be 3-6# lower due to interstring friction and machine, i.e. CP/LO. Whichever cross string is softer/stickier will have the larger differential between ref tension and resultant tension. If you assume this, then multi crosses will be lower than poly crosses. DT with multi crosses will be lower. I believe this is why the mains' feel predominate.

I could be wrong and if you have another manner of analyzing this, feel free to add your 3¢.
