Hello, I'm planning on ordering a Kanger Protank 2 for a Hammer Clone I just ordered and was looking at the replacement coils and noticed they come in different OHMs. Being pretty new to vaping (2-3 months and only recently upgrading to mechanical mods) was wondering what these different OHM levels might mean and how they would effect my vaping experience with this set up. Options available are 1.5, 1.8, 2.2 and 2.5. Full setup would be a Hammer Clone and Sony 18650 Battery with the Protank V2.
