i'm fairly new in here. i know the technical difference between a head-heavy racquet and just a heavy racquet..... has to do with where the weight is.... but what is the difference between a very heavy HH vs. HL racquet???? see some people suggesting that some of moya, roddick, dent, phillipousis may play very head heavy racquets (depends on the person posting)..... do these guys actually play very HH racquets or are they just playing with heavy even balanced or slightly HL racquets???? also, i have put lead tape at 12 noon position on racquet and like the effect on the serve, but i just think throwing the engineered balance off on your racquet is risky...... putting lead tape at 9 and 3 seems to make racquet more stable, but 12 seems to make less stable. also, if put lots of lead tape at 9/3, where should i put the other tape to make it balance??? under an overgrip or just on throat of frame. any responses greatly appreciated???? i'd even appreciate if someone (marius?? you're very helpful!!!) can just point me to similar discussions in the past.... as i said, i'm curious about playability of heavy racquets. i realize 12 noon could also be 12 mid-night!!!!
