FWIW, I slept in a Holiday Inn one time . . . and
Dave Quinn has the Nitros for $544 the pair, and will ask for what kind of riding you do, and what kind of load you most often carry (this is not the time to provide the weight you would like to have), and he says "You're 'X' on the list and I have orders for six, I'll put the orders in."
By the way, Tripp used to be on this site and sold parts and he used to provide Hagon Nitros.
Back to Dave and current time, I was third on the list and it was several weeks later the double box showed up.
This may be totally wasted in my case, but thanks to
@barbagris I had the RaceTech Gold cartridge emulators and replacement springs done in the front forks, and thought I was riding a different (much better) bike on the way home. So thinking I could feel that improvement, I thought it worth trying the rear. One silly note -- the top yoke on the Hagon is the same size as the the bottom, whereas the stock top yoke is considerably larger -- talking outside diameter here -- the bolt holes are absolutely the same. So the stock washer on top is oversize for the Hagon, something I hope to have rectified before Stearns.
