I would fix the "check engine light" on my 300k miles toyota and then buy all versions of the Malkoff E2 XT that I don't need but want to play with. After about a month of testing and evaluation, I would conclude that they're not that practical for edc use.
The now unused lights would sit on the shelf. I would contemplate selling them, but would think "whats the point, I don't need the money". They would just sit there for years and constantly remind me about how fleeting earthly pleasure is. One day, I would look up at the shelf and realize that they're not there. My wife would then tell me that she cleaned up and took a bunch of stuff to goodwill. I would probably get mad and tell her that those lights were expensive, even though we have 100 million dollars.
I would wonder for many years if I should buy them again, but probably wouldn't because I don't really like them that much. Then I would think about how different things would be if Surefire didn't hold the patent on the gas pedal tailcap. I would think about how even unlimited money can't resolve certain things, like a desire for a gas pedal malkoff.
I would probably wander off into the woods at some point and feel very sad. As night falls I would hear something in the woods, maybe a deer, maybe a bear. As I draw my flashlight from my pocket I hear the unidentified animal get closer. Then a flash as I press the tail cap. Its a bear. My heart would race as the beast moves about me, but I can't tell where exactly, because in my excited state, I'm switching back and forth between high and low with my Surefire two stage tail cap. I would never get a chance to identify the bear that would kill me that night. But as the beast is upon me, knocking me to the ground, my last thoughts would be of those Malkoff E2 XT's and whether or not the one stage and extra throw would have made a difference.
