I started out with the IGO line of RDAs, shortly after that I got into the AGA gennies then went Kayfun and have not touched a genny since. I will say that I use my RDAs as much on busy days as I do my Kayfun/Russians. I use my RDAs more on days when I am at the desk at work all day or at home. In my opinion there is no beating the flavor you get from a well built RDA. Kayfun comes close but not quite.
OP, you already have Protanks so you should have used heads. Buy yourself some organic cotton balls or sterile rolled cotton. Both available at CVS, at some other drug stores, organic cotton balls can be had from Walmart, both are available on ebay. Buy your self some 30 gauge Kanthal A1 and a 5/64 drill bit and watch some youtube videos.
You can increase the flavor and quality of the vapor of stock Kanger coils immensely by rebuilding them. You will know fairly quick if rebuilding is for you or not without buying hardware you will not use. 20$ gets you enough rebuilding supplies to rebuild your Kanger heads for 6 months to a year. If rebuilding is for you then you will have the skills and a start on supplies. You will need to check ohms, you will need to watch some videos. You will need to do some reading.
There is always this forum for a HALP! I can't rebuild this thing right post.
P.S. The Provari works well for the hobbyist, you need to build to it's strong points. I think there are only a few things better than a Kayfun to sit on top of a Provari. I am just liking my Hana V3 more right now because it is newer and more powerful

Edit: As for torching wires, you are here and most likely a former smoker. You should be comfortable with using a Bic lighter by now. It works fine for annealing the wire, it just leaves a bit of soot behind.
