Dokebilee, there are many more knowledgeable than I on this subject but I will attempt to answer your questions as best I can.
- All you need to get a Line is to get in Line. It's a new design and the first round list is filled up but the second round list will be soon so you can get in Line for the second round Lines.
- I don't know how the line compares to the 306 as I haven't tried a Line yet, still waiting for the to ship. Shpaolin will better be able to help you there. I can say that ANYTHING is better than the few 306''s I've tried so far as not a single one that I have tried so far has lasted more than 2 days.
- Once you get your Genesis style wick and coil setup the way you like it all you have to worry about is replacing the coil anywhere from 3 days up to over a month depending on what you vape, at what voltage and ohm and how heavily. I vape like a fiend and my
coils last me anywhere from 3 days to around 2 weeks.
- Mods of choice are really up to you to find what you think will work best for your needs and desires, but I can without hesitation recommend GG and Precise and if you like variable voltage a Provari. there are other mods that perform well but these are three that are built to work well and last under the harshest conditions and treatments.
