Has anyone had experience using the BOGE cartos at 6 volts? I've got an SB and some BOGEs on the way just wondering what to expect. I tried using regular 510 atties but they blew too fast, some people said they didn't have any problem with the 510s so I tried but failed. Also how does 6v with a good carto compare to using the SB with the 18650 and an LR atty? I still haven't gotten an 18650 to try out, wondering if it's worth it.
