While there are no specific bars for a CSM (other than the dual powerhead version) Some have favorites for one reason or another. Stiffness, wear qualities, etc. I'm curious about those.
Dave, I've milled with a dual powerhead mill a few years ago. It was a lot of fun. We were cutting 50"+ maple if 10-12' slabs. The 395's did the job well tho I think some 880s or 3120 would be better.
