Did you rip out a binding? Are you getting bigger boots? Or do you just want different bindings? It would help if you answered these, along with what bindings you had and what bindings you're putting on them. If they're the same and the same boot size, you can just helicoil them into the same holes. If its for a new bigger boot, then there shouldn't be a problem mounting them center again, especially if they have a different hole pattern
I've never heard about the flip idea, but it makes sense because the Anthems are symmetrical in every way; sidecut, butter zones, tip/tail, etc.
