My Buddy got the Weller Racing Springs and valving. The Quick Switch three controls the high and low speed damping. They soften it up a bit. I ordered the rear spring set and will do a comparison. I have 14,600 and some miles on mine. It looks like the bottom spring is the soft one then it crosses over to the upper spring but I'm not sure. My tender springs may need to be replaced. They will have a spring kit with cross over rings for the Talon X in a few days.
