By the way, for the newcomers, no one has talked about flavor load.
100% is mixed to Deej's personal preference for vaping. He likes a very light and subtle taste. Most people go for 125%-150%. I've been happy with 125% but I'm vaping at 4.5V than I used to so I've been opting for 150% for the lighter flavors. The stronger flavors (Apricot/Raspberry Cheesecake, Tiramisu, etc.) are still great at 125%.
Also, Deej doesn't add sweetener (which I like because sucralose doesn't like me.) As a result, his flavors never seem to get cloying. The bottom of the bottle is as light and sweet as it was at the beginning.
You can overcook a flavor. I spent a LOT of time with my Tiramisu the other day. I like very long drags and, after refilling my 3.5ml Vivi Nova a few times, the last half of the tank was a bit off -- still coffee-ish but not great. I tossed in some Tahitian Vanilla Taffy and have a scrumptious tiramisu/coffee milkshake. (When I finish this tankful, I'll rinse the tank. The next round should be as good as it was to start as the problem was me, not the liquid.)
ETA: And I'm notorious for thinking everything except the ARC and Peppermint Taffy need to be steeped for much longer than anyone else does. There are a few flavors like Bluemel Caraberry and Vanilla Cola that I disliked after a few weeks. I put them away, tried them again when I stumbled on the bottles more than a month later and have since reordered them.
