I'd be all for a double header but just play it locally rather then staging it in London or some other 'non heartlands' city.

I certainly don't think we'd have the same problems as Magic in terms of fans just watching their games because there would be a real interest to see who'd win both and who'd meet in the final. The losing set of supporters from the first game may shuffle off pretty sharpish but that's to be expected.

Somewhere like the Reebok would be decent.

Stadiums like
Reebok, Ricoh, Elland Rd, Hillsbrough, Pride Park ,City Ground for a CC double header possibly even Leicester Tigers - Welford Road

London is too far and you want a capacity in the mark of 25-35k and i reckon it'd work

WHY are the Challenge Cup semi's only attracting 10 K?

Because the RFL are not marketing them as big games. They should be huge! Played infront of big crowds.

The RFL have lost interest in any rounds before the final. Would we not be better placed in terms of sponsorship and tv rights if the semi-finals were huge games?

Arse Magic Weekend has a nice ring to it

I agree.

The two options I've liked so far are:

Blackpool semis (with a 9s tournament included to get everyone down there).

Manchester DH, with Magic in London (but not at Wembley).
