Frames came.
The differences might be difficult to tell from photos.
The Pierco frame is the one that has a small amount of drawn comb. It was the best one to compare I had around. I had forgot the last batch I ordered of Pierco I ordered unwaxed.
The acorn was ordered single wax and had more wax than single wax Pierco.
Cell walls are thicker and overall the acorn seems to be a bit heavier.
The real test will be dropping a drawn out and capped full deep from waist high to see how many ears shear off.
