Go up to A basin, east wall, or hell even pali has some great trees (lots of fun stuff at A basin). Copper bowl actually has some good parts on it. steep Trees all over brek 9 and 10, that will keep you on your toes. Even Keystone has some excellent top to bottom (off the grid) tight trees, if you know where to go. (not that I like keystone over any other resort, just using the worst example). Want bumps? winterpark, top to bottom well shaped steep, thigh burning bumps off the challenger lift, and the trees surrounding each run are tight and steep. (I like trees, in my forest gump voice). Anyways sorry you don't like summit, but I lived out there for over a decade and loved it. I also did a ton of BC skiing and found runs that would make most people turn around and walk back up.
I like Abay, and have bought season passes there a few times.
Snowmass terrain is absolutely totally 100% superior. Cirque and Hanging Valley are huge and have acreage similar to the whole frontside of Abay, all of really, really good stuff. And that's before even mentioning Highlands or Ajax.
Again, I really like Abay, and am happy to call it home for a season, but its not anywhere near to the same ballpark as the Aspen areas.
