right now im using 10wt oil in the forks with progressive springs.

filled to 14.5" from top of fork cap with air valve removed.

seems kinda bouncy but supple

was wonderin what 15wt would do with the same fill amount?

Hi, usually 10w oil with progressive springs is the perfect ride, while 15w with progressive might make for a stiffer ride. i would probably go with the 10w and change to 15w on next service, you can also play with the amount of oil you put into the forks.

You could always try the 15wt oil, filled to the same level .... if you find that a bit too harsh/stiff, try subtracting an inch of fluid and retest. Or .... keep with the10w, but add an extra inch. If that doesn't do it for ya, go with a 15wt.

You should be able to 'fine tune' it to your liking by adding/subtracting amount/weight of oil

That's what I did. 15w was a bit hard until I removed 25cc, it was perfect for me after that.
