What mountain should my Dad and I go to?

I have been lucky enough to have a Dad who has taken me skiing every winter for 7 years now. It is always one of the best weekends of the year but unfortunately this will most likely be the last year he will be able to go due to his age (55) and a his bad back. It has been a great run and we would like to cap it off with the best mountain yet. So far we have been to Alta, Snowbird, Solitude, Deer Valley, Park City, Powder Mountain, Snowbasin, The Canyons, Copper, Vail, Keystone, Snowmass and Aspen. If you had your choice, what mountain/mountains would you choose that fits me (fairly skilled, powder, trees and the occasional double black) as well as my dad (more of a smooth carver, powder and black diamond skier) that is not on the list above. Thanks r/skiing!
