Cool I'll take all this into consideration I do like the bolt and I know it's dangerous but I also do like to stack. I have a couple 5 ohm devices that I would like to run at 6 volts and I just figured the ego v is simple and can go up that high without stacking at a reasonable price. I have a twist and I like it a lot but that extra 1.2 volts is a big bump from the twist, reviews I've watched show it performing well but still not sure.
