Ride'em, Break'em, Replace'em. I have 390's and I never broke a disk, but I always have two extras just in case. They are way to cheaply priced to not have spares. Rome gave me some, so did Burton back when I rode their bindings.
Yeah having spares is no issue it is the fact that I didn't notice my one plate cracked and so when I hit a kicker I just felt the binding give out, It was freaky I remember going to carve heal side and my entire binding just came off the board. I was not amused... I guess I just need to keep a close eye on them.
No one else has had this issue?
