Roll the dice to pick one and just proceed.
I know this is out-of-context picking, but I don't think I've ever seen anyone state that A->?->C is "just as good as" a direct A->C. I would have thought it self-evident that a shorter adaptation path is always better. And specifically, I know that Philip has stated that PyProtocols applies a shorter-is-better algorithm. Having pointed this out, I'll go back to lurking. You two are doing a great job of converging on something so far, so I'll let you get on with it.
