All my experience with Deccas is very old. (But by George, this thread is tempting me... agh!) I too remember it did well in the Keith Monks (you hardly ever saw one of those). It also worked in the ERA tt's stock arm, a plastic girder-shaped device, and of all things it worked in the Sugden Connoisseur belt-drive's gimbal-bearing arm. I hate to think of how sloppy those bearings were, but the design did not frighten a Decca.
Come to think of it, I have a BD2 in the horrible crawl space that serves for a basement. No, no, no... !
