OK...Here's the bearing skinny from a true professional: Tom Haberman of ARC Cats...his quote to me: "Bearings for the high load drum & swivel are a pea green color, material is Torlon. The white ones are Delrin *( acetyl)."
There you go....like me you are all now up to speed on the proper bearings and the proper amount of brutality that they can take. Hope this closed this case.....Least I'm done!! :-)
