We mainly use 1/2" coated Geocopper from Wieland for this.
Don't make two headers, only one on the suction with an oil syphon. At the inlet, a distributor on the outlet of the TXV with as many injections as you have crcuits of course.
We installed many DX/DX systems.

So you're saying you need 70 meters of 1/2 inch dx pipe per ton? Seems like a lot.
For this setup, 4 tons of capacity equals roughly 14KW heat flow per hour. This would require 5 loops, 200 feet long each.
