For those of you who have been are they similar or is Whistler much better? I've gone to Northstar about 5 times total and am able to ride all the double black diamond trails (tech stuff on Karp not fun though), most of the new stunts, and was wondering if Whislter is gonna be fun at my level. (I'd say intermediate) I'm getting ready to reserve a hotel and a three day lift pass at Whistler and want to make sure it's gonna be something I'm gonna be able to have fun at?
