Have you demoed either of them?
I would highly suggest getting the 2010 models especially if you're going to hit obstacles with them. With the new construction, krypto cable and the sintered base option it would be much more ideal and durable for any cable use.
The 2010 Ibex is a big stable platform getting most of is pop from surface area. It's pretty quick and holds a really strong edge. With its almost featureless bottom it does feel great on sliders and you can press the hell out of it.
The 2010 One, the same mold as the 2009 but with the new and way better construction is more of a "surfery" feel, carving from edge to edge is ease. It does have a 3-stage rocker but not a crazy one. It has a great consistent lift off the wake. It does slide well and you can press it pretty well but I would really suggest you get the sintered version to protect the little molded fins.
What boards have you ridden in the past? and what did/didn't you like about them? What are your favorite things to do when you ride?
I personally have been riding the Ibex for 2 years and am switching to the 2010 Bill which is amazing!! and I'll suggest for anyones riding style.
