No need to send pics, I’m familiar with the Jones/Yes bindings. I do realize that all the current bindings have symmetrical mounting on the heel loop. But the inquiries about the bindings featuring FASE going around about “rotational highbacks” are all referring to a highback that can be rotated in the heelloop and actually adjusted, weather they have an asym highback or not. The picture of the bindings you sent (and the pic/description I replied with) was the old Jones Apollo from 2011 which did have and asym highback AND pre-rotated mounting at that time. The current, updated models only have the asym highback. In the snowboard industry the verbiage of “rotational highback” or “pre-rotated highback” refers to how it’s mounted to the heel loop, not how the upper part of the highback is shaped. I’m not trying to be difficult about this, I just don’t want people thinking there is a feature on the bindings that is not there. In the end you are right but the correct wording/way to convey the specs/tech is: the highbacks are NOT pre-rotated and the cannot be rotated, but a couple of the highbacks ARE asymmetrical with extra material at the top, lateral side to help make up for the fact that they cannot be rotated.
virtually all modern binding highbacks are asymmetrical, so calling HB asym means nothing. even the 32 FASE highbacks that may appear symmetrical, are actually asymmetrical.
the jones, NoW and yes bindings have never had any highback rotational capability.
jf show these NoW drive binding in this clip, and as you can see, there is no rotational feature with these highbacks. BTW: 2018 and 2020 NoW drive were exactly the same binding.
the pre-rotation feature with these bindings, are that they twist in the upper half and the extra extend on the outer side.
this is a screenshot of a top-view, FASE jones highback, from a CAD drawing.
the pink is the right hand highback and the ghosted blue is the left HB. as you can see this is what a pre-rotated higback looks like.
