I'm doing a little teardown/rebuild/upgrade of my Burner and thought I'd replace the 3-way with a newer Fox...but I'm not sure which is better for the suspension design. I don't really want to spend the extra $ on the RP23 if it really won't do much for me. Having a lockout isn't a big deal for me either. I'll probably look at getting it PUSHED down the road also. I use this bike mostly for longer rides or more technical trails and tend to stick to my hardtail more regularly...so I like a stiffer setup on the rear shock normally.
