For trees, the Pescado is outstanding. Light, responds well to short turns, good float- a powder ski you don’t have to ski fast.
you could also consider a Praxis Protest in shorter length. Nimble, forgiving and quite light for the size. It’s what I use but I’m heavier than you.
I’m not a fan of chargers in trees. The wildcat is good also, but I really seriously don’t like them on runouts and hard pack. Love it in soft snow though.
my theory in trees:
1) shorter and wider for agility vs long and narrow for stability
2) tips that stay up even at slow speed (that’s my beef with a lot of these recommendations)
3) surfy and forgiving…tail rocker and twin tips help.
