Hey Blue Screw, Thanks for posting that nugget of info from Bruce !
On the Double Steer issue, I think we've all fought with that at one time or another.
I know my car never does that when I have a lot of front bite, or when the dual rate is dialed down.
Maybe a different front tire with more grip, and a rear pod, sag, shock adjustment would help.
Get the car settled down on corner entry, but still have enough steering mid-corner to exit.
Gluing the fronts a bit may also cure it.
