I've been
vaping 2 1/2 years and been revamping my attys almost right from the get go. Within the first couple weeks I had a poorly coiled CE4 I was revamping to make better. I learned all I know from ECF, Youtube and still learning. I've been through all the wick phases (silica, ekowool, mesh, cotton, hemp and now rayon). I have the drippers but very rarely use them since I can build and enjoy a top shelf vape off my kayfuns. My wife still uses the protanks that I build hemp fiber coils for her. She has forgotten what a dry, metallic hit was.
I too am a kayfun addict and its going to be hard for me to give them up for something supposedly better just to revert back to kayfuns.
The next step I waited way to long to take was DIY juice. I like many have spent oodles of money on juice that is crap, playing Russian roulette with customs or finding juices that are just plain sub standard. I really enjoy the Hangsen Tobacco concentrates, they are an unbelievably great vape. I have no trouble getting nicless concentrates, PG or VG over the border just tell them its for soap making. I do pay more but I source my nicotine in Canada but the few extra bucks saves a lot of customs anxiety.
I'm totally self sufficient now vaping wonderful builds with great DIY tobac juices, wife is happy with her gear and juice....vape nirvana.
