I have an 08 SJ expert.
My experience. When new, It was ok, but not great, as I came from an 03 Enduro.
The top shock pivot sleeve, was tight creating a lot of sticktion, fixed it and wow much better.
I rode it for about three months and did an air sleeve service, and was stunned, by the lack of any grease about the air piston and can seals. I lubed them and it was like night and day better. Then the platform went out and had to have the whole shock replaced. Got that one back and it has had three air can services all with the negative air left it.
Now my friend purchased an 10 SJ expert and they ride almost exactly the same.
I think the service is crucial to the AFR and it will slowly dissipate the grease (slick honey) and negative air, leaving the performance quite bad.
In short, I would service it and see what you think before dropping $$$ on a RP23
