elasticity
maintenance (brake replacement)
din
^all of these are very important factors. elasticity is how much the binding will allow you to move without releasing. in which you dont want to pre-release, which keeps you safe. if you break a brake, you may want a binding that you can easily replace the brake. Rossi fks are expensive and a pain to replace if you end up breaking one of them. whereas marker and salomon the brake replacement is easy. Din- no need buying jester pros when you and 95% of the population dont need them. get something that isnt to high, but fits your needs. what din do you currently ride at?
examples of good bindings: Marker jester, Griffon (depends on your skiing ability and weight), fks 140, STH2 13or16
