That sounds great. The triples were a hot wet vape, that I thought was a bit strange. Maybe The carto was bad, I still have 4 left. I should try another...I'm really looking forward on giving these 2.5 a try..Thanks six...That's going to produce a cooler 'wetter" vape as well. But, the good news is that they should handle 7.4 volts like champs. My understanding of the 2.5 ohm DCs is that they stuck with the same alloy and just made the coils larger. That means more surface area for vapor production. At 6.0 to 7.4v, those should perform admirably (albeit cooler than the lower ohm DCs at the same voltage)
