I play with the Prince More Control DB 800 right now, and it's a rather uncomfortable racquet (stiffness rating of 71). I'm looking to switch to a racquet that will force me to lengthen my stroke, and in general, just a racquet to grow with. I've heard good things - many good things - about the Prince Diablo, which is a relatively old racquet. The racquet comes in two sizes: 93 and 98, but I hear the mid plays more solid and has a larger sweetspot than does the midplus. Anyone had experience with these racquets, or headsizes in general? Or does anyone else have other racquets to recommend?
