Jeff - Great review. Seems like you and I are about the same size (6'2" ~200 lbs). I'm riding the SB5c, and I'm not having much trouble with the shock bottoming out, but I do feel like it runs through the travel a little more quickly than I'd like, and I was looking for options - without messing with the sag and air pressure too much. What size volume reducing spacers were you using on this setup (I know, slightly different bike and shock)?
