HaHaHa! Rude points! Err… I mean… “Reported Post” points! Err… something…
So, I politely countered toddcshoe’s assertion that this light really needs firefly mode, and that lots of people need/want it that way. Furthermore, I said that it was possible with current BLF designed driver hardware and firmware already and suggested he could mod a light to get what he wants. He attacked me for whatever reason, then said he was going to block me. All of this is just a few posts back. Anybody can read it by just jumping back a page.
So, I’m guessing that he’s the one who hit the “Report” button on two of my posts in this thread. (I don’t know that it was him, but I’m pretty sure it was.) Full Disclosure: I did mark “Report” on THIS post of his because of his actually attacking me for whatever reason. So, maybe he decided to “get me back” or whatever. 
toddcshoe, you need to learn to talk in a civil manner about things without losing your temper. If you weren’t such a jerk, you might remember that it wasn’t that long ago that I agreed with your idea to make a BLF special with low-low modes being a primary feature. Crazy Idea.

Spartans, sorry for the interruption (again). I just needed to get that out. Hopefully toddcshoe will “Report” this post also, so I know he read it.

Okay, now to get back on topic. I really like the fins on the head, but it is my sincere wish that you do not put any of those fins on the tail. I like the size, shape, and color of the light as is. I only would like to see 50% more fins on the head, and a slightly larger switch button. I’d like the light to be built to the scale of the renders you and Andrew have shown, with a 21700 cell size tube. Obviously, these are my opinions, and you’re free to choose whether to take these suggestions on board or to summarily dismiss them. 
Thank you for bringing this design to us. I’m glad you and tatasal are in talks, and I’m sure a manufacturer will rise up to make this light for us all to enjoy and they will have it done for sure before Christmas. I’m just not going to try to predict which Christmas.
