It is MOST critical that you tune your suspension for your "style" of riding....
For example if you tune your suspension to ride alone every time you have a passenger your tune will be wrong and the resulting suspension dynamics will cause your bike to handle poorly.
You have to tune in sessions also, set your basic static sag, pick a starting point for compression and rebound, then go ride make small adjustments in both directions ( soft and hard ) and front to rear eventually you wil gather a great understanding for what is going on and be able to predict what the adjustments will change, This will allow you to pick different "groups" of preffered settings depending on the riding you are doing for the day and allow you to go back to previous set-ups when desired.
