I do not believe that Pro SDs (with their 8x8 cm rear aperture) have quite as many issues to consider when using the 6x8 back. I will defer to the experts on 6x8 backs to explain the details of their use in detail.
I completely forget about 6X8 for some reason - something new to think about and fiddle around with...

If I recall correctly, you are right about not having full 8X8 view, I studied it years ago, being obsessed about composing with what can be seen through the finder/ground glass. Currently more obsessed with lighting .
