We've just revised the Street Fighter 4 Strategy Guide for Vega (Claw).

If you haven't stopped by this guide recently, you'll find that all of his move sections have been fleshed out. They now include strategies and tips on how to use each of them, plus there's a combo section and an overview of his strengths and weaknesses.

If you're interested in playing Vega, this should give you a really good starting point on where and how to focus your energy.
