So I've been working over this 26 gauge build in my Kayfun for a few days now. I could never do 26 gauge on any other PV because my low power preference couldn't heat the wire up near fast enough. But the boost feature on the P3 solves that problem and I can enjoy a 26 gauge build. After a few days now it is a very nice vape. More vapor volume and a nice full flavor compared to the 28 or 30 gauge. Definitely a noticeable difference. It might be too much for my wimpy vaping style but not overwhelming. So I will continue to experiment with it it going back and forth between 26 and 28 gauge to decide which I like more. Maybe I'll get some 27 gauge and split the difference.
The P3 has been a God-send for those who like to vape at low/medium power levels. It has opened up previously untouchable areas of the vape spectrum.
