I think they would definitely generate interest. I mean less than two years after the first series aired their losing finalist is getting a shot at a world title against a the longest reigning champ in boxing, and the winner was offered a fight with the p4p top 5 middleweight champion.

That's a definite success as far as the show is concerned. They are bringing a load of the contenders from both series over to fight in the UK, which is great for boxing as well.

If they did a show on heavyweights I actually reckon it could be entertaining, and could create one or two fighters to watch in the future.

I'd imagine they would probably have to cast their net wider than the US though. Imagine if they found a couple of unknown eastern Europeans and maybe some big giant African dude or a fighter from somewhere completely remote, a big Icelandic blonde haired colossus or a fierce, stocky Mongolian warrior.

I maybe getting carried away a little but I do really like the idea. Another series with the lower weight guys does allow them the possibility of fights between guys across all three series, but beyond that it only serves to increase the competition in what are already very higly contested weight classes.

Surely another series around the welterweight weight limit would be unworkable as how many welter's and junior middle's can they realistically promote?

I think heavyweights could well be the way to go.
