No racquet is really an "upgrade". Unless you're playing with a junior racquet I suppose.
If you're looking to experience more of the classic "player's racquet" feel, I suggest adding a bit of lead tape underneath your grip. That will give it a more headlight balance and add a bit of mass, and won't cost you $100+.
As for needing a smaller headsize for more control, I believe that guy that just won the Australian Open uses larger than a 95" headsize, and he seemed to have a decent amount of control over his shots.
