Bottom filling the Beserker actually works a lot better, no flooding of bottom chamber, and you get more liquid in the tank.
Keeping an eye on this thread coz it's on my wishlist.
The only RTA I've got is the Kayfun 5 clone, which I love! Dwarv also on wishlist. Definately get a better flavour on the KF5 and the wasp nano/pico squeeze combo, than with my beloved Nautilus's. The original coz it's got a bigger tank and Mini's coz they are my first love and got me off smoking.
Definitely think I'm leaning towards single coil MTL RTA's and squonks in my vaping future. With the Crown's for DTL. But always my S22's when I'm lying down. But still got the Nautilus's in daily use.
I also tend to use MTL's with slower, longer toots. So if I start to hear gurgling I just blow it back down before I get a mouthful.
Maybe next month. Will live it vicariously through this thread for now. Cheers though£21.39 on Fasttech at the moment with MAP code for the 4ml

Thank you for the advice @pancser,much appreciated. My first build flooded and then leaked everywhere,I did the upside down tank flip thing whilst screwing the top on with the airflow closed but it didn’t make any difference,I shall try taking those O rings out next time.If you remove those two orings from the top of the Berserker mini (I posted above) you will not have any issue with leaking and you can top fill it @Lucas James 27
