i need some help form you guys that have a mod. I have ordered 3.7 volt mod and am in the process of ordering a vv mod. Question is what is the best devices to go with them Atomizers and cartridges or caromizers and what oms to get . Is the LR the best way to go or the Standard resistance. I am thinking I would rather have cartomizers as they would probably be less fuss and muss Can I use the same cartomizers on both the 3.7 and the vv or will I have to buy seperate cartomizers for each mod. Where is the best place to buy cartomizers as I want to save as much money as I can but I want to buy a good product also I need drip tips too Where would be a good place to buy these. One more question should I buy the 510 801 or 901 cartomizers and what is the difference between them If I go with the 801 or the 901 I am going to have to get an adaptor so I need a place to buy these to. Any help I can get would really be appreciated
