The thing that drives me the most nuts about the profile hubs is that each side has a different chainline ("44mm fixed, 47mm free"). Why, oh why? And neither of them are even standard chainlines. RRRAAAAAGH!
I think it could be because a screw on freewheel doesn't give the same chainline as a track cog and so this would happen on any symmetrical flip flop hub. I seem to remember this being an issue when people couldn't get chainlines to work when they converted a Genesis Flyer to fixed. I've never used a screw on freewheel so I'm not sure.
