Thank you Vapor Chef and it's really great to see you! I can't believe that you never gave the 901 a try. You definitely won't be disappointed but it maybe a trial because of your love for the 801. They are really hard to compete with and their widened room gives much flexibility for alterations. The only successful 7V+ atty we ever made to date

The 901 is right smacked in the middle of the 801 and a 306 in terms of flavor and actual feel. The reason why it's one of the favorites is because of it's low liquid consumption. If overfilled, it will proudly let you know. It can be a learning process especially coming from an 801 or even a 510 model.
The 306 is more like a 510 but gives off a slightly higher percentage in flavor and also a less liquid consumption. Mwa taught me: with a translucent drip tip on, fill it till it reaches the top of the bridge and vape away. It makes no mess and will last a very good session.
The Fusion has been an all star, it's much like the Boge 510, but has a more constricting air flow which also acts as a bottom leak guard. The filler is nearly identical, whereas being loose for drip friendliness and the coil is positioned vertically much like both the V2 Gold and Platinum.
Happy New year Chef and that's a mighty fine unit you have displayed there
