To be honest, Carl - my head is spinning from all the recommendations I've read on one forum or another. I'm resigned to the probability that whatever I choose will not be quite right the first time.
I like to keep things simple, so in my mind a single rate spring seems to simplify the investigation. I'll probably try the Intiminators first, and then decide about new springs. It will be more work that way, but I'll learn more. I've heard about the possibility that the Intiminators will cause a bit of front-end "bounce" under certain circumstances, and I've also read that a .050 hole gun-drilled through the bolt solves that. I plan to speak to someone at Ricor and get their take on it. Funny thing is that I experienced similar behavior after putting Racetech cartridge emulators in a Ducati Multistrada.
Time and experimentation will tell.
