I don't really like the salomon's too much, the mantras are pretty nice though, but i don't know if the fritschi's would be a solid everyday binding.
I don't ski park, maybe a little, i ski not park, backcountry and pow and drop cliffs a little, but nothing giant.
Options i can think of:
1. do nothing, ski sandstorms everyday, and mantras in pow, backcountry
2. sell the sandstorms, ski the mantras w/ fritschis erryday
3. sell the sandstorms and the fritschi(just binding) and buy duke/baron
Sparknotes: Fritschi solid enough for everyday?
