jumping straight in to one of the big boy battery mods, eh? that's the way to do it 
confused though, I thought the silver bullet runs 510 atomizers?
glad to hear it's making an improvement...but yeah, I can see where dip would be a whole other ball game. The liquid you got is a pretty high strength, but it won't replace the sensations of having that hunk o' shit in your mouth (sorry, i never have understood the appeal of that habit lol)
I bought the Silver Bullet on the recommendation of a friend of mine. In our conversations, he said he spent a few hundred $$ on other parts before he bought that, and wished he bought it from the start. I have no problem with "do it once, do it right". I spent ~$175 total with batteries, charger, e-cig, fluid, and case.
I don't know enough to comment on the atomizers, but these are what Matt used, and they work.
I chose 24mg because my doctor told me that each tin of Skoal has a nicotine-equivalent of four packs of cigarettes. Going through a tin or two daily (as well as smoking at work), I figured I would start high at first. I'm hoping that I can slowly cut back (4-6mg / purchase) until I'm done. We'll see...
As for the appeal, all the "benefits" of smoking (and then some) without the stink/smell...
