Well, glad it wasn't as much as a difficult process as I was thinking although my success wasn't that great. I had a hard time getting all my coils to light up red hot. It was either the top coil burning hot, or dimly lit top 2 or medium hot 3 coils, but it takes awhile for them to get hot. I tinkered and tinkered, but not too much success getting them red hot like the top coil. I was glad to see I am comfortable trying to do it over and over, but just didn't want to waste all of my wire trying to rewrap. I am getting a stuffiness to it, and probably not a lot of smoke. I am running at 1.8 to 1.9 ohms and currently vaping at 4.2 on my provari mini. I guess it is going to take a lot of trial and error before I reap the benefits of an RBA setup, but glad I at least tackled it. I am guessing I may not be happy with the hole size possibly. I was reading to leave the fill hole open, but that would leave possibility of leaks, right? Can't have that, but it may help the draw. May have to only use the RBA at home if it's a nice difference. Well glad to be in the family. I am underwhelmed, but know I need to give it some time. I think I have a 4/3 coi setup.
