how is this thing going to hold up in powder? I only like riding a centered stance and will avoid setting back my ride at almost any cost (probably to my demise). I am after a 'one quiver' board that can handle west coast resorts. I'm also not really sure how much size factors into riding powder. I rode a 160 k2 turbo dream with a centred stance on a (atleast) 3 foot powder day at squaw recently and didn't have a problem, even when i got to the flatter parts (though i did have to lean back a whole bunch). Two days later with just as much or even more snow (tahoe got seriously pounded end of feb and march) I tried a 155 jones all mountain twin. I was expecting great things but I suffered quite a bit. If i kept my weight towards the back constantly i was okay but any weight shift and the thing seriously nose dived. Again I was riding a centred. I' a tall skinny guy (5'11, 150 pounds) and am unsure whether height or weight play more of a factor.
Anyway this board looks seriously appealing. I loved the true twin playfulness of the evo and its ability to hold an edge, and the stiffness of the sl. It was the first RC board i had tried (only ever ridden a 157 burton un inc.). However I didn't get to try it in deepish powder (only some chopped up left overs). Anyways if I was to get the proto what size would be good for me? I mostly lap park when there is no snow or nice leftovers, but I don't want to compromise too much on my ability to ride powder.
