I use the same helmet for climbing and mountaineering, but a different one for kayaking and skiing.  Don't try and save a few bucks when your brain and your life is at stake.  I helped rescue one climber whose helmet, crushed by a falling rock, almost certainly saved his life. Kind of paid for itself right there....
