I've been vaping for about four months now and have retired my minis and moved on beyond the realm of the 510s and am now on my second eGo model. I've got atomizers with drip tips, tankomizers, and a Tube Tank. Dripping is great, but messy and requires constant work and cleanup. Tube Tanks are great, too, but the cottonfill-based ones mute the taste, lower the overall vapor output, and tend to restrict you to the same flavor for days at a time. As such, I tend to go with tanks and a tankomizer. I started with 100% VG e-liquid after having loved some of the flavors I started out on with blu Cigs, all of which are supposedly 100% VG, but the lack of throat hit and the wear and tear on my atomizers caused me to want to change things up. I've had plenty of mixes, including 70/30 PG/VG, 80/20 PG/VG, and 85/15 PG/VG. But lately, I've been vaping a lot of juice at 50/50 PG/VG and there's so much more extra vapor than at 80/20 PG/VG that the slight decrease in throat hit is a small price to pay. After trying different eGo batteries and tanks/tankomizers and dozens of juices, I honestly think a 50/50 PG/VG mix is ideal for an eGo tank setup. But that's just my opinion. The overall experience just seems to be perfect at 50/50. That's my "sweet spot".
