I am a former user of Marker Jester Schizo bindings, and I really liked them, but I see they are no longer available. I have a new pair of Salomon QST 118's incoming, and want to mount adjustable bindings to be able to play with the binding position. The factory recommended mount position of the QST is really close to center (-4.6cm), which concerns me a little on extra-deep heli/cat days where moving slightly rearward can be beneficial. Any recommendations for me on the best quality and top performing option for a demo or adjustable binding? I'm not too worried about cost, simply the best performance and reasonably lightweight. Thanks so much!
