SofaKingSickyou should just get the demo version of a good binding. hopefully someone knowledgeable on that will chime in here
RiceMarker has a line called the schizo series which not only allows for u to adjust where the bindings are underfoot but also the boot length so your bindings don't have to be redrilled. Below is a link for the griffon schizo.

Only thing I would be aware of it that some people think adjustable bindings have less structural integrity as there are more components hence it being weaker. Personally I've had no problems when I had my old schizo squires. Honestly if u were to get non-adjustable bindings you would be fine, as your feet are unlikely to grow + redrilling isn't that much of an issue tbh. Hope this helps
