Jeff: I think using a LF camera makes one a better MF or 35mm photographer simply because LF makes you slow down and pay attention to what you are doing. There are no motor drives or pentaprisms in LF, so you learn to shoot what is important instead of zipping through a roll of 35 and hoping for the best. Every LF photographer I know has set up a shot, studied it on the ground glass, and walked away without making a shot. You soon learn to recognize good images. However, I don't know if changing to LF would really solve the problem you are having with being dissatisfied with your images. You may need to give your images a good, hard look. If you like one, why? If you don't like one, why. You will learn more from the good and bad images than from th so-so images. Really pay attention to why you like or dislike an image. Does it need better printing, better composition, or was it a crap image before you took the picture. A LF can make some beautiful images, but so can a MF and 35mm. For what it is worth, I would get into LF through 4x5. It's cheaper and other than being able to make bigger contacts, it's about as good. There are many more film choices with 4x5 also.
