Does anybody ever need to force flood to get flavor? By force flooding I mean closing the air control off and hitting it real hard to pull liquid through the cotton. I am using a limitless lux dual 26650 on 130w 99% of the time with a tfv8-q4 coil (more flavor than the t8 to me, I get none from that one) and you have to hit it pretty hard with the air control wide open to get any flavor. I prime it really good when I change coils, it just seems dry and hot after 2.23 seconds. Always big clouds just not always big flavor. I've experimented with lower power and less airflow but that seems to make it worse. I did find a sweet spot with the air control and power at 90w but it didn't last for more than 2 or 3 times. The q4 is rated 50-180w and best at 90-150w. It may have to do with using double fudge, it took 1 tank of bubblegum and 5 tanks of blueberry cream to completely get rid of the chocolate taste. The cotton still looks good, a very very small section of the coil is black, I run a q-tip around in there once a day to clean it. The q4 usually lasts me about 9-10 days of 10-12 ml a day during the work week and about 20 ml a day on the weekend.
