Skied the BC Navis Freebird last season and liked it. It was pretty good all around: nice on soft/playful days in Utah, handled crud pretty well, east coast tree skiing on boilerplate skied out/thin/bumps was about as good as to be expected.
Hadn't skied anything over 96mm until those and I generally liked them. I didn't gel with the longer length (179), coming from a shorter ski (historically as well) and the tails felt a little grabby in tight, icy conditions sometimes. I also came off a Dynafit ski and missed the easy skin rip. So I guess liked them but didn't love them, though maybe it was just me.
Considering going to the Dynafit Beast 108 next season, especially since they've added some camber underfoot. But to be honest, I'm not really sure what that means or how to compare them to the Navis. I understand the Navis to be a good powder ski with some versatility due to a more traditional shape, some decent camber and flatter tails. The Dynafit would be more rockered and bigger overall, but with more camber next season might be slightly better on harder snowpacks.
I ski mostly east coast BC with some resort (30/70 resort/BC) thrown in and this winter will head to British Columbia on a hut trip so want something that will handle that with ease. I typically cycle a ski every couple seasons. I'm 5-10/170/31yo and ski aggressively and difficult terrain but not with much grace. Basically trying to decide between keeping my existing setup or converting to the Dyanfit Beast 108, which would offer a swap to a slightly shorter ski, perhaps easier turning/less grabby, and my preferred skin setup. Just don't want to lose too much ability in dicier, less ideal east coast terrain, if the Navis is understood to be better in those conditions.
Thanks for any help!
