Something to think about when using RT straight rate springs, they are much shorter than stock dual rates or HyperPro continuously variable rate springs. That means you have to put in more spacer to take up that space. It also means that the spring compression has less travel before spring bind. There was a couple of threads about a year or so about guys bottoming their forks. I have never had mine bottom and I hit a chuck hole once that launched me airborne. HyperPro flat states you won't ever bottom their springs.
Just more "stuff" to burn up brain cells on
