Wow, you put way more thought into handling techniques than I ever have. I just use my Kung Fu Grip.
Maybe you'd be better served by a headlamp, and a jig that mounts one of your Gizmos to the tripod-mount on the underside of your camera. That way you wouldn't have to manually coordinate the aim of your flashlight with your field of vision.
Is Jaqi the name of your dog, or is it the name of some outdoor activity?
Over in the Haiku High CRI thread, there is an interesting discussion of the 119 vs. 119V emitters. Is the 119V available on the 6V Makai?
this may be an obvious answer, but is the XP-G2 what goes in these now?
I ask because I adore my XP-G2 Haiku, and the Makai looks like it might be a great "next McGizmo" before an 6V XM-L Haiku or HCRI Haiku
