Hi, I'm an beginner - intermediate player looking to buy a new racket. I mostly play doubles (occasional singles), and I like controlled drops, drives, net play, and of course some smashing. Thoughts on the artery tec ti 99 4U? Would it be too stiff? Enough power? I'm currently using a low end wilson (too head heavy for me - its hurting my wrists). Definitely open to suggestions. Budget around US $100-150. Light, stiff (?), even balance (head light?).
