I think you will find that bees do whatever they want.
I have hives :
foundationless that were drawn perfectly.
foundationless that were partly drawn with huge holes.
ignored wax foundation and drawn comb on the side of the hive box.
draw double stacked comb next to plastic
draw 20+ little cross combs instead of with the cells.
just refuse to touch any plastic.
So far, I haven't found a pattern. If your bees draw the one piece plastic, then I'd go with whatever you like.
I personally, I have a mixture of all three and still can't make up my mind... LOL
I like plastic from the ability to level set, if they decide to bugger up the drawing. But generally, they seem to wax better.
I have 100 something pf combs in the garage that are about to get a liberal roller brush painting of wax...
