I'm not sure if I'm sold on the DBair yet, I've read a lot of good reviews about the Dueler and I want to try something other than Fox or the others. I've been riding my RP23 at the recommended sag for AM (.625") and even when I'm not riding hard I blow through the travel to the point where the o-ring slides off. Here are my conclusions of the Dueler:

Good reviews
Small bump sensitive
Highly active
Ti spring
Air preload (bottom out control)
Simple adjustments. Every thing I need and nothing I don't
Can be custom valved and tuned at home
Life time warranty except the typical normal wear and tear clause
They fixed the rebound issue

Knobs are hard to turn, aaaaah.....
They don't have the history/experience in MTB as Fox, CC, Marz., etc.

Thoughts, opinions, experiences please.....
