I like the string a lot. I finally settled on a hybrid with the Alu at 55 in the mains, and N.Vy at 57 in the crosses. That's on a ProKennex ki5 (100 sq.in) and has worked great for me. I fancy myself an all-court player with more serve and volley thrown in than most. I found the racquet choice made much more difference in the touch shots than these strings as I've had them in a few different setups.
I see some dropoff on it after a couple matches... personally, not as extreme as some people cite, but certainly there. The first couple hours are magic though.
