Hi I have been searching for a new racket for quite some time and I think I have found the answer (or so yonex would have me believe with marketing) aside from that I am very curious about the voltric 70. I play mostly singles a few doubles games and currently use a fake yonex arcsaber 10 for all of them. I tried a yonex armortec 700 I don't really know which one i think its the newer one. Anyway I felt a lot of power from the 700 but feel it could use some maneuvarability which brings me to the vt70. I noticed they have 3u and 4u sizes. I am wondering if the balance of both the 3u and 4u rackets is the same and I dont truely believe that the whole racquet scaled down 5 grams is going to make a big difference. Please help and many thanks in advance
