@Hoggy so I stripped down 3 different RDTAs to fresh coils and wicks and it goes like this: My 3 Charons are all set to 50 watts and my builds are all .2 ohm Dual Claptons
Battlestar RDTA: Nice vape, good Flavor and clouds, airflow is decent. The Wicking channels are a nice size, it is easy to fit some nice fluffy tails in there. The Velocity deck is easy to build on and there is room for some bigger builds. Wide bore drip tip is nice. A basic simple, no frills RDTA
IJOY Combo RDTA: These are pretty similar in everything except build decks. Even though there are multiple build decks available, it is a PITA to tear them down and fit back together. Love the Chuff cap. This is a pretty nice looking quality RDTA with Gold plated Decks
OBS Crius: It's nicely built and the airflow is more than the others, simple Clamp and Snag Goon style deck. Nicely built. I need to break it down completely to be sure, but it doesn't appear that the center pin is adjustable, so this may be a negative for some users.
So I would like to see Smoant build a better mouse trap by making a really nice Quality interchangeable deck RDTA to match with the Charons would be nice.
