Ditto for me. Haven't received my Raw Ns (aka Son of Raw, aka Wee Raw) yet, but that's also why I'm getting it, not because it's the most practical small light.
IMO the best option looks like the upcoming CR2 ION. Very bright (maybe 60 lumens), good runtime, well made, regulated, two stage, very small. It's expensive at $145, but it appears (to the extent possible to ascertain without having one) to be possibly the most practical choice in the ultra-tiny category.
However another possibility is the upcoming Peak 1x AAA Luxeon. It should be very small, yet significantly brighter than 5mm single AAA lights (Arc AAA, Peak Matterhorn). It's unlikely to match the output of the CR2 ION, but it will probably be a lot cheaper.
