In reply to UKC Gear: I'd echo Neil's recommendations here. The Eisarena area where Supervisor was had big multiple lines from WI3, and in better conditions there are similar lines at every grade up to WI7+ (whatever that is!). Mordor looked perhaps the best grade WI5 I've seen anywhere.
In reply to ice.solo: Thats right, theres a WI7 M7?? just left on Mordor and then just left again is the WI7+, neither of them formed when we were there. Just as well as then we had a nice excuse not to get very very scared. I think both those routes have mixed sections and the WI7+ has one bolt. Supervisor is just all on ice.
