Michael,
Very nice photographs. Keep going with it.
I always found the Pentacon Six to be quite adaquate for my needs. One thing to consider, is that the back can have a tendency to "pop open" if you accidentially knock it just so. The solution for this, is to put the bottom of the Everready case on it, after it is loaded with film. Then no chance of the back popping open and ruining film. I guess you could tell I found this out from experience. 😛
