I'd say that Cunningham has a great shot to make the list, unfortunately it sounds like he will be moving to heavy in the next year, two tops (based on quotes from him).
Gomez is one of the best Cruisers of all times, he defended his WBC 10 straight times with ease. At 6'4, southpaw with incredible reach, speed and mobility Gomez had it all. It's a damm shame he was a party animal who wasted much of his potential as a HV. :-(
