Yea, I had the HB diff on my Pro 3 too..but that was to solve the issue with the outdrives as they were slightly longer than the stock ones.
If they are lighter then that is good, I can't really see how they can make the diff smoother as none of the actual delrin touches the balls etc.
Before I get some I'd like to see what they actually look like and what you get, I wonder if the diff is built slightly different?
Delrin outdrives usually spin truer than composite drives. i dont think hes talking about the actual differential action but it might have a small contribution to that i dont know..
