This question is for those of you who have actually used both the 7.4 and 3.7 Delta9 products.
I am considering the HVD upgrade. I would like to know in terms of vapor production, what order you would put the combinations of carts and voltage in. I would like to order a 5 pack of carts with this order, but I don't want to order the 5 ohm carts, for example, if 5 ohm at 7.4 produces less vapor than say 1.5 ohm at 3.7, which I already have. I am looking for the next step UP in vapor production, not down.
