picture??? does the notch make it so you can pop it in and out, while it's pretty locked when the highback is vertical for riding?
i'll have to take some pictures, sounds like you have the right idea. i ran the highback screws loose and i could slide highbacks on folded down. when you rotate them up, how it hinges on the heelcup, the highback only wants to go up and forward so it stays in place.
I have a set of the Switchbacks on a Bataleon Camel Toe solid board, and loved the feeling from the get go. On the groomers the board does not shine, and maybe the bindings don't help, but as soon as I dove off into the slackcountry I couldn't wipe the smile off my face. Even over crud and wind blown ridges I found them to give me more stability/agility.
On a side note, the Camel Toe doesn't seem to get mentioned here, but I reckon it make an awesome split. I heard that for 2014 they are going to offer it with some kind if resin down the middle so that it can be split and not need any further finishing. It looks like a Hovercraft, but has a triple base wide nose that really really does let it hover over crud debris and gives it supernatural float in pow!
