PT Mike, ah, Pony Tail Mike, of course! Life is funny. I was thinking of you this evening as I was driving home from court in the central Adirondacks and passed the road to Daggett Lake. Sorry to hear about the ankle. Email me and I will give you Terence Fogarty's contact information. He can help you out on the sizing question and answer any other questions you may have about the binding. wilkins at northnet dot org You can mount directly to the ski, or you can mount to an aluminum or G10 plate and attach the plate to the ski using the normal insets. Rui and other Fogman users: You also want to watch the nylon blocks for wear. The circular indent can become oval or chip, resulting in the release pin no longer fitting snugly in place. If they get worn, replace them. Depending on how much you ski, replacing them every year or two is to be expected. You can get parts from Fogman or any Fogman dealer, such as H2Osmosis. I am planning on being at the July 9 ELR at Twin Lakes, and maybe the June 19 C. Hope to see you then!  John
