I'd wait at least a few days if I could.
I'm not sure if OBS has dealt with, or even addressed the issues with their ceramic insulators cracking.
And while it won't arrive until next week... the new (and uniquely odd) EHPro Bachelor is shipping now (Eciggity).
It was after I ordered that I saw a hands on describing it as "just slightly restricted" airflow (it's an underneath air channel, single coil). In my book that's code for "pretty damn full but can be clamped down for MTL".
I might be wrong, hence the advice to check the reviews as they come... it's feature rich and may turn out to be a winner of a tank.
