ok so i am like one week into my new habit. so i bought a blu cig starter kit cuz i understood them to be most user/beginer friendly. I do like them, but my buddy turned me on to better flavors then blu offers. So i know i can i can refill blu cartos, but i dont like the flavors mingiling. So whats the best attys and carts to use with blu? 510 something, right?
