Rear disc calipers, use Focus or Merkur?

Trying to finish up gathering parts for my "Trick-6" GT6 rear disc brake conversion.
Since it seems I will be making my uprights and caliper mounts I need units in hand ASAP.

Rotors I already have are Focus ZTS and the regular Merkur conversions use Merkur Scorpio calipers.
Merkur/Sierra parts are not so easy to get in the U.S., or are expensive.

It occurs to me that Focus rotors should work fine with Focus calipers.
Much easier to locate here, cores or perhaps useable units are $23.00 at the self serve salvage yards.

Looking at pics it seems the Focus calipers may be a bit lighter in weight but are still from a car far heavier than my GT6 will be.

The real question, anyone familiar enough with small Fords to be able to recommend one type over the other, and why is your choice better?

Other calipers that might work well?
I am hoping to have a parking brake capability since this is to be a street car.
