Try using either a 3.0 or 3.5 mm ID coil in the Siren, that should have enough cotton in the juice/feed slots. When you think you have a bit too much cotton (whatever type wicking material) in there, you'll have it just right!Happy New Year Dude!
You have no idea how good it is to have finally found something else that works for me. It’s been about a week, and the Ares is still running great! Not sure why the Siren V2 didn’t pan out, as it’s strikingly similar, but alas it’s a leaking little bitch.
