I have 2 "identical" Vantage frames. The full specs are: VTCUSTOM: Vantage Racquet (code 321104), Frame size 100sq", String pattern 16x19, Stiffness 63 RA, Length 27", Weight & Balance 310g / 11.0oz, 325mm / 6pts HL, Handle shape 2 (“D”), Handle size 4 - 4 1/2". One is red and the other is black. But...they play differently. I cant tell what it is...but the red one just seems less manuverable. I tried to find the balance point in a table's edge, and it's exactly in the same spot. Any ideias?
