Yeah I am tempted by ikon pass for the aspen option.
However the only local unlimited Ikon option that really appeals to me is copper. Eldora is a windy shithole. Winter park has too weird of a layout for my tastes and nothing there can really compete with the high alpine at Breck, the May skiing at ABasin, and beaver creek. I would stay on the Epic for those 3 things alone but vail and keystone are nice to have too.
I will stay epic and buy an aspen 4 pack if I want to go to aspen.
