Depends whether you want DTL or MTL or both.
Any sub-ohm setup will take 70/30
For MTL, the Nautilus tanks (N-Mini or N-2, NOT the N-X) can just about handle it.
If you want a tank that'll do both, the Triton 2 takes a range of coils from 0.3 to 1.8 Ohms, all of which work with thick juice.
None of my Nautilus tanks have ever leaked. The Triton 2 has occasionally leaked out the bottom airflow, but only when I put very thin juice in it, which you're not going to do anyway.
