thx for the all info. I usually adjust the stance angle myself and I find 12,12 ( or is +12,-12 terminology)working good for me. I think the point about narrower stance could be the issue. The place I rent the boards from, has boards that range in board lengths..so I guess they just have a common stance width but I could be wrong. The type of board seems to be the same across board length. So it seems the stance width could be an issue..although I thought I was comfortable with the width when I stood on it. Anyways last weekend I went back and tried 153 again. That board works like a charm...so I am good for now.
