I have it strung up at 45 in my EZONE Xi 98. I love it. Mellows out the powerful racquet. Control and power is enough for me. I'm pushing 2 weeks with the same set of strings. It didn't feel like there was a break in time needed, either.
I'm a baseliner and it felt good from the back. At the net, the string was fine (I'm not a volleyer). Serves felt good and my return game was excellent with the strings (when I didn't shank the ball). I even lost the dampener once and didn't mind hitting w/o a dampener - something I never do with polys.
I plan on buying more sets of this string!
