So I am thinking about picking up either a dual 18650 un reg or a big ole reg (Sigelei 150 or IVP3 etc). I have 1 single 18650 box, 5 tube 18650s and 1 26650. I used to have a Smok Xpro BT50 but it got knocked over and the threads are shot in it. I keep meaning to fix it but Im lazy as shit. So I was wondering about grabbing either a dual unreg or a big reg. Not really sure which though. i used my BT50 regularly with an Atlantis v1 tank, lock the buttons and shove it in my pocket, but I can always throw my Atlantis on my Manhttan and that damn switch aint gettin pushed on accident. On the other hand I have so many mechs now I keep wanting something diferent.
