put a nauty mesh 0.7 in the adaptor..
I'm a big fan of the 1.8ohm nautilus coils, I've been using them for years in other devices, but in the BB I had issues with them, they just didn't wick too well and they had a fairly short life (due to the wicking issues)... So "if" you have any issues don't fret too much, once you move to the Xeta or other rebuildables it's unlikely you'll look back ..
