@Ronaldo , Good call on that one. I just happen to have a TT Grande 115 that is 27.5". I forgot all about it being 27.5". Boy is it light at 8.5oz strung. I got it to see if my 62yr old wife of 38 yrs and just beginning to play, but has some basal thumb arthritis might be able to swing it.
@BHold81 , I took my lightest 4-stripe POG OS that happens to be in grip 3 and installed a grip 3 XTP cap on it. It is now 27.5" 12oz/340g and 6pts HL. It is strung with NXT 16g at 58lbs. I thought about restringing it but this racket has been hanging on the wall for more than year and the strings are virtually unplayed. I am going for a hit this afternoon if we can get some court time indoors. I'll swing it against my Pure Storm LTD+ and see how it feels. It might be "magic." I do have a Prince Graphite Pro OS inbound and if it doesn't weigh too much I might put an XTP cap on it as well.
All this 27.5" talk has me eyeballing my pair of Chang Ti 28" OS's along with the hacksaw. But before shortening a Ti Chang I should bring out my 27.375" Chang Graphite OS and see how it plays again. I haven't had a lot of luck swinging a 28" OS Prince.
