10 year old daughter has won a couple of small satellites in SoCal and just moved up to her first adult racquet. Bought a Head iS2 mid from TW after demo (great price and hit it well) back in Feb. but racquet has already developed butt cap problems and weird handle vibrations. I'm sure warranty will cover it, but does anyone have other recommendations to try out? What about midplus v. oversize for juniors? Your ideas appreciated.
