yonex vcore 97 and vcore xi 98
I used to play with the vcore 97 330g. Played with it for a little over a year and it was much heavier than I could handle especially after a strong session of hitting. I demo'd the 310g and felt that it was good but the vcore xi 98 seems to hit the sweet spot for me e.g more forgiving, more power, more comfortable..
Either one should work but the 310g is probably for the player with more mature, developed strokes, can generate his own pace. More like a 4.5 - 5.0 player looking for something slightly less than a pro's racket.. my 2 cents.
