Eleaf istick 60w TC

So I just purchased an eLeaf iStick with a subtank plus .
Im new to this sorry..

I was just wondering if someone can guide me on getting the best vapor production from this. i.e. quantity of vape and thick vape.

More specifically, what ohms/volts/Watts should I set it at and how much air flow should I allow?

I use the RBA Coil 0.5 Ohms.

Thanks in advance for anyone who helps.
