If you've already got a Coda with Cartels I wouldn't put a stiff binding like the SF45 on the Westmark. Neither would I put as dumb soft binding like the Contacts on their either. If you go Union do Contact Pro's. But make damn sure the toe strap fits will on your boots and prepare to deal with a terrible to ratchet.
Personally I would put Raiden Zero's, Flow M9's, Flux TT30's or DMCC Lights, Salomon Districts, or K2 Formulas on it.
