Thanks for your help BirdDog, i guess i'll just get either/or, probably both eventually haha. They both sound like great PV's from what ive heard from people and the reviews ive seen. For someone thats going to be direct dripping, do you just recommend getting empty carts and buying the e juice with it? Is it as simple as that? And when you buy packs of carts, if i were to use and fill them, do they last a while if i keep refilling them?
