I've been told the Type E is 10w and SE Heavy is 15w. I don't know what viscosity spec of the SE Extra Heavy, but I would guess it is 20w. The Heavy gives the ride a slightly more taut feel, and others have endorsed it saying it enhances the handling of the bike and reduces bottoming. I haven't given it a thorough-enough test yet, but will report back after a longer ride.
