Oh jesus, that dude can sure ride hero moguls. He's not going to hack it on real runs like Drunken Frenchman, KT 22, Gunbarrel, just to name a few if that is what they consider mogul runs in the video.
Here's some advice from an ex mogul junkie. I go for pow more often, but once or twice a season I'll blow through a serious mogul run to scare the hell out of the skiers.
For mogul riding, and I can ride 'em, get a good solid stick that has good dampening and is stable. The Neversummer Titan or Unity Dominion are going to be two boards that chew them up and spit them out. You have to be on top of your game with those boards, but they'll do what you want, ie turn on a dime.
The Flow Infinite and K2 Podium would be other boards that would charge in moguls.
A +-30 stance? WTF is that? I ride ducky and that is a rather extreme duck stance by any standard.
Suburban's Capita recommedations may be good ones too. I have no experience with Capita but he generally gives out solid advice.
Get some solid bindings to go with whatever you get. Don't skimp.
