But seriously, it was a smart move on Mag's part to phase out the 5-6 cells. the retired 7-cell Mag...well, that just sounds ridiculous. The 6D is probably up there with the Solitaire sales-wise because of how many batteries it takes. The 5D, which is somewhat more common, suffers from the same problem. The 4-cell has become the new maximum size, which has been the opinion of some flashaholics for years. The 3D is a personal favorite of mine because for thirty bucks I can get six NIMPH D-cells and have a working light with ready back-up cells, or two lights at once, no money down on alkalines. With a 6D, I'd be paying thirty bucks to power a single light for who knows how long, with no spare cells. I'll get the NI drop for my 3D, see how I like it, and when Mag comes out with theirs and if the reviews are good, I'll pick that one up and use the NI for an emergency kit light or give it off to a friend, at least it's better than incan. Sure, Surefires blow everything Mag has away, sometimes you need something that can break bones AND light up a room.
