As a flashlight manufacturer I wouldn’t bypass springs. There is a big risk the bypass gets teared off, as it happened in my L6 after a few days. Most people here can easily do bypasses, and non flashoholics won’t mind the litttle difference in output.
I replaced the bypass's in my L6 - very thin, not well soldered - poor quality. Did not have problems with them torn off though, or any bypass I've done with silicone covered wires, and I've done hundreds at this point.
We thought the double springs would be easier, maybe cheaper, like in the Mankers. That's why we spec'ed them.
As I understand that without double springs or bypasses, the Q8 protoype puts out well over 5000 lumen, I would like to leave both out to have the springs as proven effective fuses. Modders living a bit closer to the edge will have soldered them in in 20 minutes.
There are workers doing this bypasses manually, some are skilled, some not. The Q8 even needs 4 bypasses. Just a question of minimizing warranty problems.
This is my thinking as well. I see no reason to demand they bypass the springs as long as they can handle the current, even if run with a single cell (if that option is going to be advertised with the light). If the springs do not melt in these conditions then I would just leave them alone.
From a manufacturing perspective double springs is the easier and cheaper option as well. That can simple be reflowed onto the PCB and needs no manual labor / skill.
Yeah, not that it’s likely to happen but I’d pay 10-15$ more to get it with the new 90CRI 219C 
How about that? Enhanced Beryllium Copper Battery Springs
In the OP we called for "Double springs with the smaller being Phosphor Bronze springs". I'm thinking we should stay with this approach - this was decided on way back.
Yep, I'm emailing a whole bunch this morn with our manufacturer contact about the prototype and where to go from here. There were a bunch of things done he wasn't aware, and was out of his control then. He just wanted to get the proto out to us in a rush as-is, and realizes there's a bunch of shortcomings. Things have changed over there since, so it seem we have a much better line of communication right now. If nothing else, this prototype has kicked this off -- all good.
Sounds like a really good situation, not the details changing of course, but more importantly the unerstanding and interest to deal with it.
Phosphor Bronze is also good!
Please add me again to the list for another light. Thank you…….Jesse

And OP list updated!
Wow what a huge number
I have yet to post the pics of the prototype on CPF, I think it will be ore then 18 when done 
Please add me to the list!
Hi,
My name is Keith, and I’m a flashlight addict.
Please add my name to the list.
We’ll forgive you if you forget
You can add me to the list !!
Please add me to the list!
750+ Woaw Woaaaaw Waaaaaarg g g!
Good job The Miller! 
I hope the very noticeable interest in this project and the SRK style flashlight type will help motivate a better then decent manufacturing process and put it back into the glorious position it used to sit.
I just think that when the final light is ready to go this GB will set a record for selling 1,000 lights.
Everything about this light along with the price makes it a “Must Have”
