That's pretty much all true Daxx. Wlad used to use every punch in his arsenal...if you watch the fight vs Ray Mercer you'll see Wladimir pretty much at his best pre-Manny Steward.

Right now with Manny he uses the jab and a pawing(at times) left hook and the right cross and that is all. Wlad did have the chance to use some different punches vs Tony Thompson though, he worked the body a little bit.
