I'm thinking of taking advantage of the Head IG Extreme MP deal since I'm currently using the Head YouTek Extreme MP right now. I have a setup of Prince Synthetic Gut Duraflex and I love the setup and racket thus far other than occasional wrist pain, but that's probably technique. Is the IG version a "better" version compared to the YouTek? Is it stiffer feeling or softer? Is there more noticeable power?
