Great info above for those who don't know about the EST model. However, in my initial post I was not referring to the difference on the EST.
I don't have an EST board, so I know to not even look at those bindings. Right now Pac.Boarder and Comor have two Burton Cartel bindings non-EST, both differing models. The alternate to the regular Cartel appears to have more padding on it, at the same price. I couldn't find any info online on this alternate model.
