I'm looking into purchasing my first copper mod (most likely a clone) and I want to get one with 20x1 threading so I can easily find a hybrid adaptor for it. I was all set to buy a XXIX clone but I'm having second thoughts. I don't want to be limited to hybrid only, as the possibility of getting juice down inside the tube is a drawback for me. Also, as beautiful as the XXIX is, it seems quite fiddly and I don't think it would be a good first copper mech. I'm looking into a Paragon clone, as I believe the original is 20x1, so a 1:1 clone should be as well. I really like the Vapetech pegasus, but I can't find out what threading it uses. I know Fusion Mods sells hybrid adaptors with different threading options, so if there is one that fits the Pegasus and one of you guys knows about it, I would very much appreciate the information. And if there are any other full copper or close to full copper mods out there that can fit readily available hybrid adaptors, I would love to hear about those, too. Thanks for reading and trying to help, guys! I really love this forum; it's a great community and it's wonderful having so many kind, knowledgable people in one place that are down to help each other through the bumps in our vaping journeys. Peace out!
