its hard to narrow it down to one but here is a list of some good ones
-Look PX 12 Jibs- I have these this season and i love them, they are a really light binding, super durable and definitly have a good release pattern too. (check my reviews if you want some more info on them)- I've heard a lot of good things about Rossi Scratch Bindings- Also look into marker Jesters or Griffons- The Salomon Z12, not as durable of a binding as one would like but my friend has them, no problem yet, supposedly the lightest binding on the marker? correct me if wrong.
