i have some sppp laying around and thinking of hybriding with syn gut in the t10v mid. i've tried ash monogut / syn gut hybrid and liked it for spin but the vibration started annoying me. so should i try the poly hybrid again or stick with multi? btw - i've tried poly in the LM4 (stiffer racquet) and felt little or no vibration. could it be that flexy racquets don't work as well with polys?
