Poles break both of my thumbs and last year, i break 2 pairs in less then 2 months so i decided to start skiing no-poles. It doesn't rly change much, this year i bought K2 poles that just cant break *40$* and i enjoy skiing as much, it rly doesn't change anything on rails, may be a bit different on jumps but after few runs you ajust yourself and its just the same.
Respect skiers with and without poles, they are still all skiers.
