I've always thought it would be more beneficial to have one really strong show rather than trying to even out the talent.
Personally, I would move Triple H, Edge, Big Show, Miz, Morrison and Vickie G to Raw. Then move Rey Mysterio, CM Punk, Jack Swagger, Christian, and Evan Bourne to Smackdown. I would also send Cryme Tyme, Kofi K, Noble, Hass, Kozlov, and Snuka to ECW.
