I have the Penske and the Progressive and running tests on them now. The Penske is a wonderful shock but may be too much for my messed up back. It sure handles well, and I have 4 springs, so you change them out too. Not sure what I am going to do, but the Progressives are leading for now. I'll let you know after our trip out to Gettysburg.
Looking for a good replacement for worn out stock units , any recomendations ?

I've had Progressive 440's on my last 3 bikes and can vouch for them being much better than stock. I recently switched to Works Street Trackers and they're most definitely a cut above the PG's. As far as I'm concerned anything would be an improvement over the stock shocks.
