Thanks, ive been reading the forum for a few days but yes im sure ill have some questions, like when i need to get new coils i wouldnt know which ones. I also have a luxe 80 for sale in the classifieds and i have some opened juice which i dont like and wont use so if anyone is interested....Welcome @Kevinc1977 !!!! Well done on kicking the stinkies too!
You have made your way to the rabbit hole, now it is just a matter of how deep you want to go...
What @ivc_mixer said is spot on, as long as you use freebase nic (not nic salt) you can run it in any setup. But for the sake of your lungs surviving, try and keep it at 6mg and below if you going to run it on sub-ohm. There are a few that tempts fate by going as high as 18mg freebase on 0.3ohms at 35W, but if you aren't looking to grow some hair on your chest I would not suggest it. Rather keep the nic salts to podkits too.
As for burning taste on your rebuildables, make sure you saturate the cotton with juice before you start vaping, same with pod kits and stock coils (for which you fill the tank and let it sit for 5 to 10 minutes). Also start at a lower power level and build your way up to where you are comfortable on the Variable Wattage setups.
And if something is not working quite to your liking, ask questions, post pictures, there will always be someone to lend a helping hand over here.
