elastomer change
I went from the 5 to the 3, and the operation was easy. the ee silk+ suspension is so very well designed that it would seem impossible to get it wrong. I've been known to do that, but not in this case. easy-peasy! one comment, and not a complaint, is that it would be nice to have the # stamped on the elastomer.

I changed the elastomer in my seat post to a softer one. Even though I had the right one for my weight, it made a big difference in comfort. Surprisingly, the shock stem made even a bigger difference in comfort, now the harsh terrain is much more tolerable, and I can ride longer.
