Welcome to the forum!
on the supposed 'lack of weight and instability" of the AP, I was watching a young guy playing against Sam Groth at the AO wildcard playoff yesterday using a stock frame (not a Bab, but still) that is lighter than an AP and he seemed to be doing just fine.. Maybe Sam just doesn't serve as big as those heavy hitters of the USTA 4.0 league in NorCal?
it's in your heads, people!
