I don't disagree with you, max, that the 100 sq in, 16x19, yellow and black, super stiff frames have been pushed in front of kids for the past several years, and that they, in turn, can impart more rpms than a midsize racquet. But to call it "unplayable" is a bit of a stretch. It does take more developed strokes to wield a midsize racquet, though
To the OP: no offense, but if you're not A) Sponsored, B) Have the last name Safin - then you shouldn't be breaking racquets because you can't keep your temper in check in the first place. (insert some emoticon that displays that I'm halfway kidding)
Haha...max, I guess Safin's midsize Heads were
unplayable if he kept destroying them all.
