I've broken 2-3 ribs on 3 different occasions but never on a snowboard. Been really lucky, I've been riding for 14 years, never worn a helmet, taken some really nasty spills and diggers and have never sustained a serious injury other than a broken nose and a couple bruised tailbones. Hope you feel better soon.
When I was in the Army I knew a man who had 3 rules about sex, one of them was "quantity not quality". I really regret not asking him what 200 pound twins would classify as.
