Just got done playing 3 sets on my newly strung Blue Gear Ultra 17 (Full bed). Seems to have (maybe) a little more spin potential than my previous strings (Spiky Shark, Signum Pro HEXtreme, PHT), but not much more. I did notice that after the 2nd set, my shoulder was sore (and that never happened with any of the other textured stings I have tried before. Overall, not a bad set of strings, and not as stiff as I thought it might be reading the feedback on the original Blue Gear (so maybe they did soften the Ultra somewhat). I have another set of BG Ultra that I will likely hybrid with a softer set of crosses on my backup racket and see if that helps the shoulder issue.
