I'm w\notter. As mostly an all mountain rider, half the width of a thumbnail on each end of the board shouldn't be an issue. That said........... if you've really got buyers remorse, Colorado Board Shop and Evo each claim to have 150's in stock. Full price though, unless you've got some codes or coupons. In the end, it's your ching, and you might as well be happy and confident in your choice.
