Looking for a backup mod - must use cr123a batts and 510 threads

[Fat_46]

I'm currently loving my GLV-2, and can't foresee changing. That being said, my biggest fear is a catastrophic failure. I'm looking for input on a backup system.

I'm already invested in protected cr123a batts and SmokTech tanks, so I want to insure I am using compatible technology.

With those requirements in mind, what do you suggest for a reliable "backup" system? I'm not opposed to any mod style, and welcome your input.

Thanks in advance!
