That's the thing with being a successful professional... it means you rarely have time to try out new things that are at the core of your game. I mean I love hitting with mids too... I can/have easilly beat players that I am marginally better than with one but it's those who are just or good or better that I require my mid plus... Though there are days even a big bubba cant help me! Realistically Fed will have more days when he is sub par as he gets older so maybe he will have the time to switch if he gets knocked out of wimby before the quarters... otherwise it is only going to happen after the WTF's if ever. I believe that part of the reason Connors stayed in it so long was his willingness to switch frames (and his incredible drive to compete).
