parkplaygroundliterally 100% personal preference. at the performance level of both bindings, it all comes down to what type of feel you enjoy more since both bindings give different ski feel*for park skis*. If this is for powder, technically speaking, Marker is far superior to FKS for power transmission, ease of use, drill hole pattern, etc. Although many people will say that they have never had a problem with FKS on Pow planks.
Actually very true , and if in case you lose a ski putting it back in pow the fks is a fucking problem because of the heel piece! I agree with this guy on the jester being better on pow
