I only got the springs from Jer and installed them myself and set them up to his recommendations, and I am happier than a pig is sh.......well, you get the picture;) . Anyway, Jer is awsome. The suspenders work wonderfully. It was such a night and day experience after I set them up. The first serious ride after that was at a place that beat the hell out of me the last time I was there. This time, no problem. I felt and rode so much better and I'm attributing at LEAST 95% of it to the suspension.
