Marcus,
Thanks for explaining why the lighter oil works better. Now to try it out. My track is semi rough, dry hard pack, with medium to small jumps. 25 and 20? Or maybe lighter? I'm at 6.6lbs with yellow front and blue rear on springs. They seem to work well but that's with 32.5 and 27.5 so would the lighter oil be better with a lighter spring or are the two not so closely related? How about the Effect on traction roll or go with heavier sway bars. Ooogh its all so complicated it makes my head hurt! Of course it is 3am on the graveyard shift:0
