Yeah, based on BA's review, the problems seem to be more related to implementation of the regular binding parts, i.e. that could almost be a review of a regular type binding. If they were able to for instance take a 390 binding and convert it to this system, then I'd like to see a review.
Having said that, I still don't think I'd buy them. Without a definite benefit over other bindings that I can see, they're just a gimmick.
Illegitimi non carborundum
I hate the parts between winter...
