Gee I guess I hate “the best”, sure as much as you hate “Proprer MTL”! It’s a bit restrictive.
And when it comes to restricted airflow RDAs I believe there are plenty of good options some of which have been quoted in this thread.
@The best “ is like religion and ideology, it’s just not the right material for a good discussion point but it’s a great starting point for a fight.

The shift is great for a few puffs, drip for 1/2 hour or so and rewick for a different juice. I don’t Squonk and I don’t believe it’s great for squnking but it sure has great flavour and highly versatile airflow. I love it with a super long pipe style aluminium drip tip.
