A quick back story to start. I was a 1-2 PAD smoker for about 5 years. I found vapes and quit smoking. I was able to stop vaping and smoking for 18 months until I picked up smoking again for a few years. I have once again been able to stop smoking and started vaping again. Simple transition, some willpower for sure, but I have kicked the habit completely. When I started vaping again I purchased an Istick 50w and a troll. Have been using 3mg liquid only. It's been about six weeks smoke free again and I want to, not only upgrade, but reward myself. I read and read and watch reviews non stop, my head hurts from all of the stuff out now. I use my mod consistently at 45 to 50 watts. I have a 0.4 dual coil build and a chuff top. The heat from the vape is less than perfect, but I like the vapor production. I am interested in temperature control as well. If I need to buy two mods to have everything I want, so be it. Not that money isn't an issue, but right now it isn't a factor. I have been looking at IPV3, Sigeli 150, IPV4, Mech Mods, you name it I have looked and can probably tell you the specs off the top of my head. I just can't decide! I need your help ECF! I know I want at least dual 18650, as my Istick lasts maybe half a day until I need to charge. Good flavor and large vapor production atty, temp control, and good ergonomics. Thanks in advance for all input and help.
