I am 5'10", 155 Lbs, advanced rider, I picked up the 154.5 cm.
This is hands down the best board I have ever ridden. Magna traction for east coast is a must, it actually turned ice into powder, I thought for sure I was going to wash out on blue ice, but it was solid. I could charge hard on ice all day long with confidence.
C2BTX is great, fun surfy banana between the feet, with a nice poppy camber under each foot, this board feels great and really does it all.
I can't wait to take it out west next season. I would recommend this board to anyone.
GNU you guys ROCK!!!
