Replying to Whitewalker 121?

Looking for a new deep snow ski, and im looking for as loose and pivoty of a ski as I can get. most my powder days are in steep tight terrain where you might get up to high speed for a second but then have to shut it down again. plus just maneuver around tight trees and terrain. and if i do get into more open terrain where i can open it up, i still like that surfey, ski from the center style.

it seems to me like the 121 has gotta be about as good as it gets. but since ill be mounting close to center I'm a little concerned with the length. I'm 5'11 165, so not huge, but typically a ski too close to 180 feels a little too divey.

Also looking at the reckoner 122, line outline, maybe the rmu professor? anything else out there I'm not thinking of that i could look at?
