Its not just about with "a" friend. There is a point of diminshing returns when you go shorter as a taller rider. It is due to the length of lever(body parts) in relation to Flex pattern of the board. A taller rider is able to flex a shorter board differently than a smaller rider. This also happens in the reverse when getting too long of a board. I've seen people try out to the extremes on both. And have tried this myself. In the case above the width of stance while important is not the most important aspect I was focusing on. If he goes to short he is going to loose stability for the bigger jumps and park features. Yes he could go down to a 155cm board in a wide and be fine but going that much smaller I personally would want to demo first.

Reason: first sentence sucks and still does.
