I have a joyetech 510-t battery and charger, and I want to purchase a good cartridge to use for vaping waxes. I have been looking at the SToK F5 Funnel Cloud Cartridge (with 510 Threading) but the best price I can find for that is around $30 each. I don't care so much about price (to a degree), I want the best cartridge that will last the longest and will produce the best vape. Can I simply modify an e-cig atmoizer to use wax?
