After a decade on BMW M groups and forums, I've found the rod bearing dilemma to be excessively religious in nature.
I trust in science.

ACL Racing Series
Australian made.
ACL is recognized as a premier brand throughout the motorsports world and engine builders.
Their coated bearings combine ACL’s tough RACE Series lining and overlay metallurgy with Calico’s CT-1 coating.
CT-1 is a Dry Film Lubricant coating that helps reduce friction and abrasive wear. It provides intermittent dry lubrication and is not affected by dust or dirt.
It's what I run in my M engines.
