Thanks for the feedback. It is always good to hear of a real success
rather than a theoretical answer.
Flat plate is what I am planning, to get the lowest ESR. I have already
cut squares of LDPE 11.5" on a side, to be used with heavy Al foil, 9"
wide. Depending on how thick a stack I think I can handle mechanically,
I may divide the plastic up and put two caps in parallel, or I may be
able to get it all in one.
