I currently carry a Leatherman Serac S2 in the sheath with my Leatherman multitool. I like the clicky tail switch, and the 2 levels of brightness, but I have to admit to feeling undergunned with it's output. My present thinking is to replace it with a Peak Eiger, equipped with the momentary tail switch, and a Prometheus Lights titanium pocket clip. I like that the Eiger is US made, has a wide range variable output, and it can run on several different cell chemistries. I'm starting this thread to gain some input as to the qualities of Eiger, and any possible alternatives.
