I run a 500/800 spring combo so my set up is a bit more track oriented then yours, but I would agree with a lot of your comments above.
Compared to the Dinan set up and KW CS set up I previously had, the RS1s really are a big step up.
I would stiffen up the shocks a touch more, I found a good mix for me is 15 front and 17 rear for some tracks and reverse it for others actually, depending on the track and the conditions. The shocks run at the stiffer range with zero problems.
I have the RD bars sitting in my garage and Im going to install them in the spring, we see how those change things. One step at a time.
