Sorry, but it sounds like you've been hanging around Derby too much.The_Lecht_Rocks said:balance damping and compression combined with regulated rebound will lead to a better balanced and better geometrically affected frameset.
hence, it's better to mate two suspension systems that work in harmony with similar principles than two that aren't or don't.
a better geometrically balanced frameset will corner better under load and provide more gradual feel when pushing the front past adhesion. the idea being such that the frameset remains balanced under compression and rebound and utilising simailar systems (i.e. coil sprung suspension designs) will lend itself better to tuning and set up than using air springs / coils springs.
all imho of course.
