Replying to Pow binding

Looking for a binding for 117waist
these r gonna b pow skis , maybe some back /side country , possibly heli , cat or mountaineer, but 95%, primarily resort

Any and all input appreciated , experiences personal and other really looking between sth2 and shift ....
I know nothing of touring bindings , no experience with shift or sth2 going off what I’ve read and heard
I’m leaning towards the STH I really don’t see a need for the shift But I don’t want to miss out on it as I don’t have a dedicated touring set up yet though I have no immediate plans to tour
I have Rossignol track 130 boots
