I have 3 strings that I'm going to try, all of them hybrid with synthetic gut at 57/56 on my Prince Exo Rebel 1-Gamma ZO Power 17- I notice on the package it says "string at 10 percent less tension than usual". This is normally a big warning sign for me because that means it will lose tension quickly which i really can't stand. Will i have to string it at 52? That seems too low for me. 2-Gamma TNT2 16- No concerns about this one, just wondering how it plays. 3-Babolat Xcel Power 16-Same question with the TNT2 I can generate my own power, these are just the ones that came with my stringer. Not the Babolat one, though.
