Are you Nathan the NETVaper guy on YouTube? If you are I've been watching a lot of your videos last couple of days - fantastic stuff.
When I started this quest for my new tank thought slide top to fill was high on the priority - but it seems there's a dearth of tanks like this. But having looked at other options I'm now finding that larger capacity than 2ml is a big priority. I'm a bargain hunter too lol - so currently looking at:
The Bi2hop (though the bottom fill is putting me off a little)
Hellvape Dead Rabbit MTL
Arbiter Solo
Nevermore MTL
Some kind of Kayfun clone - though I know little about the Kayfun options.
Something I've noticed is that of the tanks above is that many of them don't come with bubble tanks? I tend to rattle through a tank if it's only 2ml - my Ares Finale is only a 2ml tank and I'm filling that all the time.
Any other ideas and comments are greatly appreciated.
