I had the chance to demo both these skis in 182 last year, but briefly and not on the same day. I really liked both, almost for opposite reasons. Skied the Shoguns on a not entirely fresh day, and they were incredibly fun in the developing bumps, really poppy and playful, easy to bring around. I got on the Belafontes in a foot or 2 of not-superlight new snow, and they made it easy to initiate a turn in the thick stuff and then felt really powerful and solid once they were up on edge.
I'd kind of like to just get both pairs, but they're a little too close to each other for quiver work. I'm leaning toward picking up the Belafontes for bigger days (and backcountry) and maybe looking for something narrower than the Shogun for hardpack and bumps and a little more playfulness when it's not so fresh. Maybe a Dynastar Sultan 94 or Slicer, or Moment Tahoe, or Salomon Sentinel. Or would it be smarter to go wider for the big ski if I were to go this route? 182 Atlas? Katana? 6th Sense Huge?
I'm 5'11" and under 150, and ski around Tahoe.
