I gave this question a lot of thought, and read the entire thread before posting... I owned an early SWM Ti that went back for flickering, and own a V10A and an R now. Both with McGizmo pocketclips, which make them far more secure for EDC in my opinion. I like the variable control, I like the design and construction, I like the output of the SWM lights, and do carry them occasionally. My Haiku XP-G rules my EDC roost, however, for the following reasons: Beam quality, which is second to none. Build quality, also second to none. Rock solid. The McClicky switch, which is fantastic... Pocketclip, again fantastic. Reliability, not even worth mentioning. Anyone had a problem with one? The biggest reasons, though, are as follows... 1. The entire light can arguably be taken down to component parts in about five minutes, O-rings, boot, switch, LE, reflector and lens separated from the body if there is a difficulty. 2. Parts- availability from several different places, all common items, (O-rings, boot and switch, clip and screws, reflector, lens). 3. Aleph LE, and E-series compatability, perhaps two of the more widely available, moddable, and useful/ reliable platforms out there. God forbid Don is unavailable, there are several fantastic modders here who understand how these work and know them inside and out. E- series? How would you like that, sir? What color and battery configuration? If need be, I have an Aleph CR2 body, stock 1x123, 1x123 and 17670 SF bodies, 2xAA Ti body from Don, and had a 1xAA TB body at one point to run this on. Commonality and compatability are wonderful things. The end-all, however, is that Don is just an Email away, if need be, and is fantastic with communication, not just when you're buying something. I don't need to send my light to someone to have it sent to Don on the off chance there is a problem. Sorry for the long-winded reply, I think that's everything...
