163 for you is big. Powder only kind of big. No surprise that it feels slow to respond.
Cobra 158 would be a good choice for trees and tree powder, good on groomers, and not a lot of switch. I'm 200 lbs on a cobra 161.
Can't comment on the other boards, no experience with them.
Edit: woudn't suggest a twin, since your switch so little.
