I only carry both the LS and AAA when casually dressed and I'll be in the dark for extended periods. The LS goes in a pocket with a wrist lanyard. The AAA is around my neck on a longer lanyard. Normally, though, I prefer to travel light and quiet. I carried the AAA on my keychain since shortly before it came out. After getting an LS I carried both it and the AAA for a while, and found that the LS is much more useful. The AAA just doesn't have the power and throw for use in the mixed light and distant situations that come up often in my work. I love the AAA, but the LS was fighting for pocket space with my multi-tool, so I ended up replacing the AAA on my keychain with my smallest multi-tool, a Leatherman Squirt P4. I'm pretty happy with my setup now.
