I think you are partly joking here, but still. I can tell you have never owned a TM26. The light is phenomenal. Very comfortable to hold. It is one of my go-to lights for night hiking, and if it was even a little uncomfortable, that would not be the case. And you haven't fully appreciated how good a voltage indicator can be until you see the OLED in person.
Yes I am partly joking of course, but I'm serious about the fact that a 4x18650 light is a huge light and judging by most of the Recommend Me threads, far too large for most people's usage. I think something a bit more pocketable with the same charge indicator may get more love.
