Well with the MDC HA 2AA your limited to the multi mode AA head. Which is great btw. But with the VME and 2XAA you can pick any M61/M91 and use that. It’s best suited for the 31 series do to the AA tube but you can run a M91 with a couple 14500’s for full power or a M61 with a couple primary AA for reduced power. The VME is very versatile
Just one level with the M31. You can get L or LL LLL versions for it for lower output and longer runtime though. It’s pretty much a one level bomb proof light. No fuss no muss. Honestly if you want to go the AA route the Malkoff AA is the way to go. High is close enough to the standard M31 and you get huge runtimes at the two lower modes.
But isn’t that the idea? They disappear in pockets, are barely noticeable, and are very light. And I prefer the cigar grip for these mighty pocket lights. But I too carry the aa malkoff size bodies probably more than the 123s.Ya I know what you mean; I have rather big paws & my M31's are in 2xAA/3xCR123 bodies - 1xCR123 hosts are too short for me to handle comfortably.
If you know how to use the web way back machine you can fine that information. I haven’t a clue how to do it tried once and damn near drove me nuts!
