I know you all know this by now, but i have to say it anyways.
I love my KL1's, i have a E1L and a E2L, both with 2-stage mod tail caps.
Size, throw and runtime make these EDC's for me.
And now with my new RCR123's, been thinking of removing one of the 2-stages, just so i can actually use up some guilt free juice.
Bought some of the sweet 750mah's from John @ Lighthound, and found some local 650mah's, charging these up right now.
Not sure on what kind of run time yet with either, i will see. Unless others have some stats handy already from thier own.
