Take a look at a few of the players rackets or tour rackets, and request a few to demo. I had a deal with Wilson as a junior, then played Head rackets in college. I've hit with nearly every racket on the market (between college tennis and full time instructing) and while I do have my preference, any of the big brand's players rackets are comparable.

I will say that I played with the head Prestige midsize (93 sq in) in college, and haven't played and practiced at near that same level since graduating. I have found I play much better with the Prestige Mid Plus (98 sq in), or Head Radical (100 sq in) now. I can still play at a high level with the 93 square inch head, I just find a little more success with the forgiveness of the 98 or 100 sq in head, when I much preferred the feel of the 93 in college. I still have 7 Prestige Mids and 6 Prestige Mid plus rackets in my racket bag, and will probably be set for life on rackets. Demoing a few will give you a really good idea of what works for you.
