Would a 162 of this board be good for me...
Would a 162 of this board be good for me if I am 6'1, 190 pds, 13 size foot, intermediate and prefer to ride powder, fast, some trees and little park?
thats a toss up! a 162 will actually be a little bit big, but it will be very fast and stable...might not be nimble enough for trees or park tho....now the 157 will be nice and manuverable. but lack in speed and stability
I'm about the same build as you are, with a 12 boot, and I ride a 162 all-mtn pow stick and it feels fine for me. The only reason I don't take it in the park is because it's "pow-specific" and I don't want to obliterate the base. Other than that, it's fine in powder and great all-mtn.
So I'll say 162 is good for pow and speed, maybe a tad long for park.
I think the 162 would be great! Directional for speed and maneuverability in the trees and still a totally capable board in the park. Sounds like Park is the least of your concerns so go with a board that will excel other places but still be alright to dip into the park AFTER your tree run!
