Your opinions on which film camera to sell?

My gears are very similar to yours.

Three F-100, M645Pro, and two DSLR. If I were to slim down, M645 would be the one on the chopping block. I hardly use it anymore... I am often amazed of what I can get out of 35mm format. I keep my M645 for those special situations where larger film would be preferable, like studio portrait sessions. (that hasn't happened in the past year or so...) Then again, I may go even larger.... (oh no... not again!)

It really sounds like you already knew the answer when you typed your question.....

I much prefer printing from a medium format negative, so the darkroom experience would decide the question for me (with respect to the 645).
