I've been nearly that heavy myself on a 157. My powder board is a 164 and can be a bear to throw around in the trees sometimes. No way I'd want to ride that big of a board everyday. My old NS Heritage was a 160 and that was about perfect in terms of freeride sizing for me.
I never intended to be that heavy. Took a little adjusting to travelling so much for work. Had to cut back on the eating out.
