I love the idea of a 44mm, like on my zeiss conquest, have both a 40mm and 50mm VX-III, that 50mm is big! I have a swaro 50mm and it seems smaller, so I think the zeiss at 44mm, maybe their 50mm is smaller too, but 50's are just too big for me most times.

Round seems to always win out over the years...not sure I'd worry about speculation of a non-round seal though, til it happens or many other guys are complaining about it.
