Last season, I demo'ed quite a few skis over several days, including powder, heavy new, and hardpack/groomed. I narrowed it down based on my desire for a powder ski that would also perform acceptably in other conditions. Four skis have a tip rocker profile, width/shape, and ride that I like: Line Sir Francis Bacon, Armada JJ, Salomon Shogun, and Dynastar Cham 107.
The Bacons were immediately beautiful, quick-turning, floppy, and very forgiving in powder. For me, their turn radius on groomers was a little too short. The JJs were fun, soft, schmeary, and had a springiness that made me want to play around up on the tips and tails. If I skied with a pack of snowboarders I'd have picked the JJs for both ride style and looks. The Shoguns were ugly, stiffer and with a better carve feel on the groomers, which I happen to like. The Chams were the stiffest yet and had an ability to really carve the groomers, but they lack twin tips and cool graphics.
What really set the Chams apart for me was their aggressive feel. Powder? I no longer eschew the number 11. I think it must be partly because they're stiff, and partly because there's no twin tip sticking up in the back and vibrating, but I want to charge the bumps and open the throttle on groomers. The tapered tail still allows quick turns (something my otherwise similarly-shaped, stiff, speed-loving La Sportiva Hi5s won't do well). If I encounter some crusts or chunks I feel like they'll blow through comfortably and then they'll allow me to quickly dump the speed when deemed necessary.
Apparently, I'm more truck driver than artisan baker. Its always a matter of preference, but I haven't felt this way about a pair of skis in a long time. I love them!
PS there are several other skis in this category that deserve a look. Two that I particularly regret not being able to try: Rossi S7 and DPS Wailer 105.
