I'd go with the 157. It's plenty stable, has great dampening (up there with Ride and a tad under NS), and from a swing weight perspective, the blunted tips help there. I have ridden a lot of boards, and it's honestly my favorite board. You can charge the heck out of it, but still have that freestyle side to the board.
I weigh 174 and am 5'11 for reference. It's perfect for me.
