Sick bindings for an allmountain ski, adjust em forward for hitting the park, if it starts to snow just slide them back for pow! They are really easy to adjust, literally 1 screw in the toepiece that moves the whole binding.
They are pretty heavy, but it isn't too bad compared to the normal jester. This is because of the metal construction, and several parts that are metal for added strength like a top piece to clean the bottom of your boot on.
They are pretty bombproof, although they have 1 weakness in that the back piece is floating, aka it is not attached and if you rip the metal cord that holds the two parts together.
Altogether a sick binding! If you want an adjustable binding, this one will be the best!
