On my new Rome 390 boss' I can rotate my highback to 0* 4* 8* and 12* (degrees). I have never had this on a binding before and don't really know what difference it makes. though i have not changed it yet because this was my first day riding them today. does it make them less flexy if you change them? it seems like it would put tension on them.
What does it change in you riding?
