well from my understanding the more narrow baseplate makes for a stiffer baseplate, older bindings had really thick materials so a 8in or whatever it was hole pattern was needed to get the footbed and overlays and everything in there now that materials are getting thinner we can use a more narrow hole pattern, yea sucks in the short run till its been going on for a few years and everyone has switched over but long run i think its good.
as long as hyperlite gets with the program
