Sean,
You and me are thinking alike, baby! The real sleeper body for the KL1 is the E1 or E2. Besides your stellar observation about the clip, a clipless body allows the light to be picked up in any sort of fashion and no matter how you grip it, it's the correct placement. There is no need to roll the light in your hand to orient it so that the clip is at the base of your fingers.
This isn't a mere rhetorical observation 'cause I've got two KL1s, an E1, E2, E1e and E2e and I've played with them all. Hmmm. It seems like I've got this thing for the Ex lights, doesn't it?
