I want to get the most out of my vaping experience. I probably sound like an idiot but I'll ask anyway. I've been using a 510 regularly up until I got my SB earlier this week. Other than the constant battery swapping everything has been excellent. My question is this.. are 801 or 901 attys better than the 510's? I've been searching and I haven't found anything that really answers my questions. I've been on the same 510 Atty since early November and it's still kickin out vapor like crazy and measures out at 2.9 ohms. I do vape constantly (too much sometimes!). I read somewhere around here that the 901's carts hold more liquid and have to be topped off less. When I run my SB at 6v I get massive throat hits and vapor but in the long run I don't wanna constantly run at 6v mainly because it burns up juice quite a bit quicker. At 3.7v It's better than a fresh charged stock batt. But I find myself vaping more 24mg than my original marlbro 18mg to get that extra kick. I've tried various cart mods from PTB, PTB+Straw, Tulle, Polyfill batting etc and to me they're honestly all the same. So I'm just wondering if I'm getting as good as it gets or is there better without costly experimentation. Hehe if my wife only knew how much I've spent so far "experimenting" I'd be WakaDEAD . Thanks in advance for anyones help.
