I rode K2 IPO's on the Ultra Dream and they are really tuned well for powder focused all mountain boards. So those for the Charlie if you wanna do that. Otherwise the Lights will fit really well on the Charlie too. If you go that route for the DOA I would look into K2 Formula's, Salomon Holograms (which would also be rad on the Charlie), Flow M9's, or Malavitas.
Cool, awesome Nivek I'll look into the K2's and Solomon's for sure. Flow's just don't do it for me. I have no idea why, but I seem to write off so many binding company's without even looking into them. Glad you are here to point me in other directions.
