Ive done 2 or 3 powder runs on the Bowls at Breckenridge and I was starting to get some bad leg burn. it seemed like the tip sank a little bit if i wasn't leaning back a lot. maybe i just need more time on the back slopes?
On a board that has no taper or some kinda weird pow shape, you're gonna get leg burn no matter what, setting your bindings back helps a lot were you centered?
If you also set the bindings back, I say get a p0w board. I bought a charlie slasher last year and it was life changing. You spend more time riding the board than worrying about keeping your nose up. Price is right too $399
For the record, I am by NO MEANS an expert powder rider, I've only had 8 days total riding the fresh and deep. The last two days on Charlie were magical.
