I haven't tried the silvers I have with a 9sp cassette, but I do think the 
granularity of control they yield is a bit coarser than what I get from 
some old suntour acushift 7/8sp levers. I was using those older levers with 
9sp successfully for a while until I got a new Suntour XCD to sub out my 
old xc-pro rd, and went back to indexing with shimano levers.
