How are the expert runs at keystone?

Specifically how would you say the trees are if you hike behind summit house towards Bergman bowl?

I usually spend most of my days staying in the trees on outback (love the grizz/bushwacker glades). At this point I want to start testing out the more difficult runs but want a gut check first.

Are they fun, and any recommendations about where to go or what to avoid?

Appreciate any advice you can share!
