Looking for advice on next ski destination

Looking for advice from the collective wisdom here on potential ski destinations for 4-5 days with my college-aged son for spring break (second week of March). We've skied Breck, Vail, Copper, A-Basin, and Alta, and looking for something different that is on the Ikon Base Pass.

We love long groomers, bowl skiing, glades, don't mind some moguls. We are comfortable on blacks and skied most of Copper except some especially steep mogul and glade runs, and didn't get to check out the runs off Three Bears--they looked a bit too hairy for us.

Thanks!
