Thank you for the link, I have read this material as well as Dixon's article in the 2001 Journal - the lift lever flange friction is not specified anywhere that I can see. Renner does give the spring tension adjustment numbers but I do not have a gram gauge to do that.

The Renner parts are about 4.5 to 5 grams from the factory - they are a bit tight in my opinion - should I try for about 2 to 3 grams? I am curious because the 4.5 gram is consistant for the entire set with very slight variation.
