Your probably more qualified to answer that than I, I’m guessing in your opinion Armadas do? Haven’t ridden many armadas, especially across different snow temps to tell if they have “fast” bases, I’d def say they don’t have slow bases...
my 2018 chronics def feel like they do not have a slow base, so they maybe do..and I can’t comment on rails, but the bases and edges have held incredibly well to snow snakes and rocks.
I say dollos bc it seems op is 75% park, which is more the dollo terrain, whereas I’d say the chronic is 70/30 all mountain / park, however if OPs style is chargy, jump lines and all mountain go chronic, if your more into butters and rails then jumps and all mountain the dollo
DolansLebensraumDo chronics have a good (fast) base? If not go with dollos
