I am going to replace my fork springs and need advice. I weigh 155# and ride single track and jeep trails. I have gone on different web sites and ran their setup for forks. MX-Tech suggests .40 Race Tech 41.5 I talked to a guy from Factory Connection and he said I should use .43 and lower my oil level to 150 mm. He said a .41 was going to be way too soft. Now I am very confused any suggestions?
