I was watching some videos on Youtube and one particular video said when that you set up your bindings, the last thing you should do is rotate your highbacks so they are parallel to the edge of your board. I have not been snowboarding for very long so forgive me if this is totally newbish, but does everyone do this? I have never seen it mentioned before. Mine right now are in line with the direction of my foot.
at 6 dgr I would prob leave them the way they are, its not a exact science , just look straight down over the binding and if they are close then leave it, they are not hard to do either , its just two screws at base of the highback so you could always test it and move it back if its TOO much when you switch it. but I would move them on any angle over 9 if it looks like it need it.
Yep, I rotated my high backs on my +12/-12 stance. I'm pretty sure most people (at least my friends) don't bother too much with this so it's not make or break especially if you're starting out. However once you do it, you don't have to mess with it again. And in my mind I'm getting the best performance from my bindings. Theoretically it helps, but does being 6 degrees off from parallel really make that much of a difference prob not.
I, too, never knew it made a difference, but alway wondered why the bindings were like that. I did it, though, based on the video and while I haven't actually tried em out yet, they did feel like they make a difference when I was fit testing in my living room.
