Fun deck, I was stoked to ride the 159 at a Demo back in February. Board has a great medium flex to it, not stiff, but not soft either. It is perfect for sliding rails and boxes and has great snap for popping off of kickers.
I love the 85a slimewall on the board, the dampening it provides the board is great! You don't feel all the chatter/vibration that you normally get in the park. I held up great as I took the sidewall into a couple of boxes pretty hard and there wasn't a mark on it. The feel is just amazing too, you can really feel how your edges are responding and spinning is so much smoother that I normally feel.
I have 10.5 boots and had no issues mounting up on the 159 at all. Great board to slay the park with and was fun to dork around with on the trail on the way to the terrain park.
