I have never purchased the double heavy from Acorn, just their 'standard' heavy waxed.
I will state this: the first year I ran Acorn, I took three over wintered nucs and moved them into ten frame boxes, and put Acorn foundation on one side and Mann Lake on the other. All three drew Acorn before touching ML.
This year: when I boxed nucs, I did the same thing but with Acorn and rolled over with my wax Acorn. They pulled the foundation with rolled wax first yet unlike the ML did not ignore the 'standard' of the Acorn.
