Good choices, i don't think you can go wrong.
I ski the volkl explosiv in a 180(i'd go longer next time around) and one of my good ski buddies skies the sugar daddy.
the explosiv is awesome, really good float, and a really strong ski. it has minimal side cut but is really fun when you get to open it up(you can parallel carve through piles of snow). basically, it is the stiffest, meanest, nastiest powder ski you can find...imo. i have hit a ton of rocks, done turns on a rock face, and the skies takes it great.
the sugar daddy is also sweet, strong, and skies well. my buddy puts his through hell and they take it. he skies them straight onto concrete and they still do the trick in the powder.
so, you're looking in the right direction and i don't think you'll go wrong with either. i love my volkl, and i don't have to have stupid atomic bindings on them.
any more questions?
