Chris, I really liked your blog on tail weighting. I just discovered it, I believe you wrote it several months ago, but this is the direction I have gone with my racquets. I just have switched to the 99s, and have added about 1.5 oz to be tail, to bring the weight up to 12.8, and yet leave the swing weight about the same. I love this set up. It was easy for me to do because I like to build up the butt of the racquet kind of like Gasquet does.
