at a large alpine resort (l2a) and over the course of a week, i saw 6 guys on f2, 2 kesslers, at least 6 thias skwals and a pogo.
f2 are a big brand on the european continent, and a popular/easy/safe choice for many.
for 4 years i've learned and been playing on that sort of poor surface, and ice etc. took my first trip abroad for snow, to the alps this year. i was bored of perfectly groomed snow by 10am on day 2. think of it as a challenge.
just returned from a week in les deux alpes. saw many (5+) riders on thias skwals,
shared some ruts with a two of them, witnessed a guy zoom down a mogul run on one. didn't see what boots he was wearing.
does it recover its camber if you take all the hardware off? you could always have a new one made with the same topsheet as current, and then claim you just had it glossed to keep the snow off.
you can marginally change the height of the cuff a little further with them, and of course the cant angle .. both arrows pointing down i think adds more height, but also changes where the cuff pivots from as well.
no more suggestions beyond that though, i assume the liners are pretty beefy.
