Honestly joe, i really don't see the point of cropping your images coz' they look good on its own format. But i do have to say there's a bit of flare goin' on with the images. i hope its due to the lens, which can be easily solved with the addition of a lens hood. but i experienced some of this same problem recently with my leica M6, which is not due to flares, but light leaks. yeah, light leaks on leitz, can you believe that? very distressing!
I do own a very old Mamiya 645 camera as well, which i rarely use that much. But i have to say, shooting with a 645 has a very different feel to shooting a 35mm camera. first of all, the reflection of image from the mirror of a medium format camera feels like a 'movie'/moving image. Does anyone of you feel that? That aside, i also feel like i have more freedom in terms of the composition. With 35mm, i either compose 'horizontally' or 'vertically', but rarely tilt my composition, though i do that every once in a blue moon. However, because medium format is a square format, i am more laid back in terms of its composition, i never really bother it to be a perfectly straight or upright composition.
secondly, i personally think its easier to shoot with a 35mm format using a wide angle lens, then crop it to whichever way you want. I simply think cropping images (of a medium format) is a bit of a waste, but the resolution of a medium format is definitely much better than a 35mm if thats wht you want. Like David said previously, perhaps the anamorphic lens may provide you with a much sharper and crispier images, but does it really matter?
Lastly, i don't know if this may be of any relevance to this whole discussion. But go watch a couple of Wes Anderson's movie (shot by Robert Yeoman) and Stanley Kubrick's; i believe most of Wes's films were shot with anamorphic lens whereas Stanley kubrick's films were just clean 'square' format (apart from Space Odyssey of course). I still think the latter stands out very much (not because he is Stanley Kubrick), but i do believe sometimes when our visual aesthetic are so used to a certain kind, and we look back at the old greats, you can't help but ask yourself, why do i shoot it this way, and not the way it is? Perhaps the content will speak for itself, NOT the format.
P.S. 'The Apartment' dir. Billy Wilder, photographed by: Joseph Lashelle; is another old greats that uses anamorphic to a good extent and purpose. I hope i am right so far, but correct me if i am wrong, thanks.
