| Since when did the weight of the rider come into setting the damping on a shock with a given spring rate. The damping is there to control the spring and the forces transfered to it relevant to the weight of the unsprung mass, the speed your travelling and the size of the bumps.
Sprung weight including that of the rider just determines how much of your suspension travel is already used up and therefore how much you have left to deal with what the unsprung mass throws at it.
Altering damping settings to compensate for a incorrect spring is never going to lead to the best handling settings.
All production bikes are a compromise and all you can do is tweak what they have given you to get the best out of what you have available.
