I'm thinking about buying one of these. I tried a friends the other day with a HH.357 1.5Ω LR atty with some diy fruit punch juice and I was completely blown away by the vapor, th, and flavor. The other mod I am considering is the Silver Bullet. Does anyone know if there are any significant differences between the Bolt and SB besides the price? Other than the price, it seems to me that the main difference would be the switch and the fact that there is an extension that can be used on the bolt for use with more than one battery type and voltage.
