Trying to figure out the rig or flavor you like before you have tried anything is pointless. It would be like trying to figure out if you like a certain type of food based on the packaging. Cartridges, atomizers, driptips, wich is the best way? Might as well flip a coin. What flavor is the best? Ha! Might as well ask what food or beer is the best. There is a reason why there are hundreds if not thousands of flavors out there. Also a reason why there is PG and VG based liquids and every combination in between. What works for me, probably won't work for you. I started with a standard eGo with cartridges. I didn't like refilling the darn cartridges all the time and purchased 2 different kind of cartomizers. After a few days I figured out I don't like the cartomizers. I'm back on the cartridges and want to try the drip tips. To me the most difficult thing is finding that perfect juice/e-liquid. I'm still searching for it. I have 4 or 5 juices I really enjoy but, I havn't found one that can get me through the day without mixing or switching. I plan on finding it eventually. I have decided to stick to a 70vg 30pg split. I think thats what works for me best. It took me a few weeks of going from one extreme to another. 100%pg (thoat hurts after a couple pulls). 100%VG (so thick that it just doesn't work well unless you drip it.) So, as you can see I'm still trying to figure it out after a couple of weeks of having the tools. Its an experiment, and every experiment will be different for each individual. Sorry for the rant, I drinking decaf coffee with Irish creme while vaping. Its a really nice combo.
