Solis or Adamek would have been the best choices outside the Klitchko's of course.

Thompson won't happen, Ustinov is a K2 fighter so you have to reckon if he refuses to fight Wlad or Vitali he'll refuse to fight Ustinov.

Sam Peter is still a good fight IMO, he's got power, a good chin, and he can box a bit.

Eddie Chambers wouldn't be horrible.
