What are the advantages of these...should i still rotate the highbacks so that theyre parallel to the board (like traditional highbacks)

CheeseForSteeze

They conform to your calves/ankles better since your leg will angle in toward your hips. This angle will depend on your height, stance width and style. Rotating them typically is still done so as to compensate for the angle the feet which is mostly independent from those other factors.

I think almost all modern bindings have asym highbacks. Even if they look symmetrical, the flex pattern usually gives more in one direction than the other. I've heard people saying that you don't need to rotate (ex union mounting guide video), but I still do it because I think its the best of both world's; tip to tail movement for buttering and stiff heelside response.

Edit: Hmm, now that I thought about it some more, perhaps I'll rotate less on my back foot to see if it gives me better ollie response. Edit: nevermind, that makes no sense for duck stance.

Why not?

Asymmetrical means there is a left and right binding. They are not the same for each side. In the past you could just rotate to goofy from reg without taking them off, the highbacks were the same. Now they are not the same, one left and one right. Travis Rice is famous for having his old green mismatch cartel bindings on opposite sides ( or he had some super one off magic).

I like to rotate, but I don't make it perfect, just flush with the heel cup.

theyre a-symetrical to offer support where is needed and to offer relief where that rigidity is not needed. if the bindings offer a roational adjustment than you should. its proper setup technique.

think about it.
to manipulate a snowboard to make it turn you lean on your toeside edge and heelside edge.
Your heelside turn depend on your highbacks to put that pressure to the edge. If the high backs are angled they arent efficiently directing pressure to the edge.

I don't either. It is because my stance is wider than my hips (as most people's are) which makes a "A" shape. Rotating the highbacks parallel to the heelside edge of the board takes a decent amount of the upper cuff of the boot out of the highback, even more with a wide stance or with a canted footbed (it is the footbed that is canted and not the entire binding). To get all of the performance that you can out of a highback, you would need you boot's upper cuff as centered in the highback as possible (until my hips are 25" wide my leg will never be straight up from my bindings). Is this making sense?

Just to add to the confusion, I figure if you add forward lean to the equation it gets more complicated. I realize these are small adjustments that may take a very discerning rider to notice, but if you have high angles (say 15 -12) and aggressive forward lean, a high-back parallel with the board edge may squeeze your boot down at an uncomfortable angle, making your knees point further inwards than your toes.

I'll definitely play around with my angles this season, will leave them on the default setting for now.

Forward lean is for hard-booters.

I keep unscrewing the glad on my burton chick binders because I imagine there is some forward lean out to get me. They will break at some point i imagine.
