Your timing is perfect, your analysis superb.

Separately I emailed Lon Kennedy at Nova Cycles, which is another framebuilder supply company. Here's his response just an hour ago:

"All of ours are cut and have never been rolled. I think for CrMo material rolling is not used. For mild steel where it is beneficial to take cheaper material and cold work it to a strength makes more sense."

I think I'll go home now, as I've filled my daily quote of learning a new thing.
