I bought a 15lb Machine today. It has a 2.5" pin and 3 oz. of topweight. I was thinking of drilling it up 4 1/2 x 4MB, but on the sheet, this layout would give a hook & set finish. By my reckoning, isn't "hook and set" an end-over-end roll? I just want to make sure that I don't lose the backend reaction because I ended up drilling it with a 4" PAP to MB. That's my question.
