I can only comment on the BOA's, as I have K2 Raiders. They are super smooth. People complain that the single dial BOA boots have pressure points, but I have yet to experience this. Stupidly fast too, which I like. While my friends lace up I'm already waiting on them. I also don't have to worry about them getting loose, because as they loosen up over the day, I just turn the dial to tighten them back up.
