I am a flavor chaser/mouth to lung vaper, I prefer the restricted draw and I am usually in the 10.5 - 13.5 range (rarely above 15) depending on my build and liquid. So far I have tried the following regulated mods in chronological order: innokin MVP, innokin iTaste 134, Provari 2.5 and Provari 2.5 mini, Semovar, Futura 20, ipv 2, SXmini S class, and the Provari P3. I noticed that watt for watt (i.e. using the same wattage with the same atty and liquid with different mods), the Semovar and the Provari give me a better vape. Granted it is a subtle difference, but it's a difference nevertheless. I don't know why, but I guess the nivel chip and the provari chip do a better job at regulating the current than other chips; including the dna and the SX chips. The Eye and the Dicode line reportedly do a similarly good job, but I haven't had a chance to try them. Has anybody else noticed the same thing?
