This is a tempting light. If it just had dtp, a tailswitch (additional, not instead), and of course a good driver. A BLFA2! I guess the tail switch plus usb charging gets pretty long. It's already a little long. Wouldn't it just be too easy if parts were a little modular, like they sold tail-switches that fit their clicky lights that also just screwed on to this? If someone sold different head sections with zoom, reflector, usb charging or not, e-switch or not (maybe combine the last two options), that all screwed onto the same tube? An 18650 mix and match set. BLFAX? Too much to wish for probably.
Oh yeah, and the other nice thread on it here (which is the one I thought I replied to but whatever):
Supfire A2. Supfire's cute little zoom 18650 side switch.?
