I ride a Never Summer Sl 155 and also weight 170. I'm 5'9" myself, but I wouldn't worry about your height too much. The 155 is the most fun, versatile and bad-ass board I've ever ridden, although admittedly I haven't ridden that many. I live in NYC, and it tears it up all along the east coast. I took it to Breck last year also, and got a foot of snow a night. I had no trouble at all staying afloat. Its the perfect board in the perfect size, in my opinion, so go out there and kill it!
