I just remembered something. Most MF SLR systems have interchangable film backs. If you bought into one of those systems, you could have different film backs for different development needs...N, N-1, N+1, etc. You could switch film backs when you encountered different lighting. Then you wouldn't have to compromise on anything. You already have two TLRs, so you could do a simplified version of this already.

Hmm...I knew I needed an excuse to get an R4A.
