re: Good protein/snack bar for skiing

seriously, though, you should look into energy supplements used by folks like endurance athletes. Things like Hammer Energy Bars or Clif Shot Roks/Bloks (which I love - you can just pop one in and suck on it for 20 minutes) or maybe even energy gels (GU roctane is often compared to crack in a bag - it's that good). Lots of people have trouble stomaching the gels but they are effective and easy.
