It has been a milestone for me this month. 6 months off of butts. I started with the 808 and have tried the 901 and 510 atties in many configurations, volts, resistances etc.. in my quest for the best set-up. After reading here about the 'socked' carto i decided to give it a try. I think it has been the balls. I have not had any problems ripping the filler out of either a coolcart or a turbo while leaving the inner sock intact. I occasionally get some leakage and that ususally coincides with a little gurgling. I keep the carto upside when I can. I connect a metal drip tip which I believe makes it easier and acts as a heat sink too. Pulled the wick out of one the other day and it wasn't burnt, just darkened from the juice. I like this set-up and have been using it as an exclusive all-day vaping apparatus. I would be intersted to hear from others who also use this set-up. It seems a lot cheaper and easier than buying atomizers and dripping. Your thoughts?
