Hellafornia. Formerly stumptown.
I took the fork entirely apart to rebuild it and the comp/rebound cartridge calls for 10wt oil. I have 5, 7, and 15 and was wondering if it were possible to run the 15 to firm up that side and then the final fill up just use the 7wt like called for?

Or would it be possible to run the 15wt throughout and firm/slow things down abit or would the viscosity be too much for the valves and harm them?

medford, or
I used 15 in my 40 and honestly didnt notice any difference in dampnening. I dont really turn my knobs though, so I may notice a difference if I fiddled with it.
