It seems like yesterday but in fact it has been a couple of years since I modded my MD4 Super (and a few other Hound Dogs) into the 3x18650 configuration by bolting an Everready extension to it. I am pleased with the results. I am pleased with the runtime and the lesser load on the cells.

I think 3x18650 goes well with the Super. It accommodates the larger drain and extends runtime. Batteries are taxed less. And recharged less often, which extends their lifetime.

What I am not pleased about is size. The 3x18650 is as compact as a golf club.

The other day I saw a 3x18650 side-by-side config and instantly realized the Malkoff line could use such a configuration. It's kind of short and fat but ultimately *a lot* more pocketable than the golf club I have now. And I think there are certain benefits to going with the 3x18650 config. You can keep the lumen level the same as what it is in the current Super, or bump it a bit into 1800 lumen territory. The reflector could be made huge with an impressive throw. Or go with several reflectors. The options are many.

One unexpected benefit of the 3x18650 side by side is that it can really easily tail-stand while the 2x18650 and such struggle doing so. Yeah, I know about the tailcaps that accommodate it but the side-by-side design is as stable as a coffee mug. That was the specific feature that sold me on the design with the added benefits of increased runtime.

Additionally, it has to be spec'ed to run on either 3x18650 *or* 6x123 cells.

having considered all the facts, seems 2x21700 is a better idea.

My vote would be once again for a 2x 21700 body. Approximately same runtime as 3x 18650 and for me a more elegant form factor. Also more versatile as suited for other heads and even more if available also as 1x 21700 body.

Interesting point you make.
I get the virtue of the 21700 cell. I can see the 21700 cell is the future.

Google trends produces an interesting analysis, thus far 18650 far outnumbers the 21700.

However, I think I will agree with you that the 2x21700 configuration is a better design / feature request than the 3x18650 configuration. I would think that 2x21700 will end up being a lot more popular than the 3x18650 that nobody will buy, essentially.
