Do you have a favorite BB configuration?
I've only tried a Comfort, Racing and Exocet bridge. It's still early in my BB experience but just strictly from a MTL vape point of view ... I'm enjoying the Racing bridge with Kanger RBA head.
On the Racing and Exocet, I've used 29AWG Kanthal, 7.5 turns on 3mm and it comes out to right around 1.7ohms that I'm running at 7.9-9.6W. The Comfort bridge houses a 1.8ohm nautilus coil.
I can't say about flavor because I only vape non-flavored 50/50 @ 12-18mg. The Racing set up just seems to have a little bit more volume and density vape for the same inhale effort and the same or similar BB and airflow settings. But there are so many variables, it remains to be seen if that is consistent as time goes along, I guess.
The thing is though, if I'd never tried but only one of those three ... pick one ... I'd have been happy with it. I'm lucky to have the opportunity to try three and be so picky.
