Copper sounds more like what you are looking for than A-Basin. Lot's of terrain there, and it also has pretty much exactly what you are looking for.
A-Basin is great, but it's small. Not a lot of black runs there that are not bumped out to some degree.
Then again, the same can be said for Copper, but the back bowls after a fresh snow are pretty soft. If you are willing to hike a little, Tucker mountain can be a great experience.
