When you say carving groomers will suffer, are you talking about a softer edge to edge feel or the lateral stiffness? Cause I think the edge to edge or response should be similar but have a softer lateral feel due to having better natural board flex.
Toe to heel edge to edge... a softer binding high back and baseplate are going to flex instead of pushing your energy into the board like a binding with a stiffer high back/baseplate.
I have ridden EST Cartels... more board flex as they are essentially baseless (well close enough for me). Toe to heel response was decent.
