I recently picked up a 160 Salomon Powder Snake.
1) Camber is not rockered or reverse. It's flat and almost camber like.
2) Stiffness is NOT medium-stiff. It's very soft and has tons of flex. I would give it a 4/10.
3) Float is great - Equal to the float of my 156W Lib Tech Skate Banana, but smoother and doesn't push or plow the snow with the rocker like the Lib Tech. Because it has the flat profile.
4) Pop is good, popping up and slashing pillows is so much fun with this slithering menace!
5) Does okay in the mid-day chop and crud. I wish it was a tad more damp and stiff to plow through chunder - but it gets the job done.
6) Overall a smooth buttery pow stick that is lots of fun.
While waiting for winter to show up here in Utah, I rode this board a few times at Brighton on groomers. I was really surprised at how fun this board was just carving and blasting off side hits. Carving was good for a powder board, but not GREAT.
Now fast forward a week, a giant storm rolling in off the pacific, completely pounded Salt Lake City, and the Wasatch range of Northern Utah. 4 1/2 feet of snow fell in 4 days. The first dump was some of the heaviest, wettest, stickiest snow I've ever ridden - truly 'sierra cement.' I was expecting a little more float, as my Lib Tech Skate Banana was about equal in terms of float. But those are some of the worst powder conditions a resort can have.
Fast Forward two days - Brighton, Utah gets obliterated with 30 inches of Utah's famous super dry, light powder overnight. This thing chewed up the pow and spit it out like it was nothing. It floated like a dream, slashed like demon, turned on a dime, popped and smashed pillows, ollied over snow covered trees, buttered the pow like it was grandpas toast. After a few hours the freshies turned into chopped up crud, this thing GOT through it, but I wish it PLOWED through it. It's a pretty soft flexy board, so it wasn't the most stable - but it got the job done.
Overall I give this board a 4/5 stars, my only complaint is I wish it was a little more damp and stable while plowing through the mid-day chunder. But on the fresh snow, this thing is just too much fun. And for under $400 - it's worth it for a fun pow stick.
Let me know if you have any further questions.
