[nevermind]

I find it entirely possible to keep the left wrist level when moving the hands from fix to mid body, whilst keeping the clubface square or even open to the plane line. I do that by not only bending the left wrist but also turning it. Now even if I'm wrong and that isn't the case, I still don't see it as a problem worth worrying about. Adjusted address is a compensation, we have many alignments that we don't want anywhere near impact, yet it works just fine. We start with a bent left wrist and make it flat, why not also make it level (not that I think that would be neccessary)? How much of an impact could that possibly have on ball flight and repeatability? I reckon if a golfer doesn't like the look of a closed clubface at adjusted address, so be it. Take the grip at Fix and manipulate the face square as they move their hands to mid body. JMHO. Maybe we should all just start from Fix and avoid any possible complications/manipulations/malalignments...
