Demoed an AG200 yesterday since I wanted to get a feeling of a heavier Aerogel (didn't have a chance to try adding weight to the AG100 I demoed). Of course, it played differently because of the the string pattern and larger headsize, but I could feel a little more stability with the higher swingweight. It still had the great feedback that felt from the AG100, but I'm starting to wonder if some of the "feel" that I'm getting is actually the vibration from the racquets striking the tennis ball. Perhaps the more stable and heavy the racquet, the less feeling you get out of it? Have any of you done a "feel comparison" between a stock AG100 and leaded up one?
