In reply to Andy Moles:
Ok you've tempted me.....
A few additions to your list....
Guillotine on carn etcheachan, much better than route major
Great Overhanging Gully, beinn bhan
Man of War, coire scamadal, skye
The Bewildabeast, ben nevis
These routes are better than....
The genie (really?)
Route major
Polythemus gully
Quartzvein scoop
The seam (really?)
Good list, maybe a little heavy on the conventional / well known.... I almost throw in the Clam, lochnagar and Square cut gully on creag a choire etcheachan as they are cooler routes than conventional stuff like indicator wall and stuff in the norries, but the climbing is as good.
Cheers
Andy
