I do not post much in the strings section, but I had to post this! Just tried Pro's Pro Vendetta in my YTPP at 52#'s in a full bed. All I can say is WOW! After 2 hours of hard hitting, the strings have not moved at all. This string is as comfortable as any poly I have played. It produces just as much topspin as well. Surprisingly, there is good pocketing and feel (which I do not say often with polys). For $55, you can not beat this poly. I used to play Tour Bite, but that is a thing of the past as Vendetta is 1/3 the price. Got a couple other sets of Pro's Pro to try, but I think I have found my true love.
