Where were you riding at Beschatten? I just took my 154 Proto to an ice skating rink. (i mean big boulder). I thought it handled well in the horrid conditions. Once i had confidence in the ride it actually held a very strong edge. (unlike my friend who washed out on his toe edge, smacked his face and slid halfway down the hill, err mountain.)
Only thing i had to get used to was the dampening. Im coming from riding a Rossi Retox where you feel everything. The proto felt a little numb to me.
