Only started vaping in March and already built up a silly amount of gear. Out of the 11 mods I now have I only use my 2 Kennedy Vindicators, Kennedy Roundhouse 24, SX Mini MX Class, LV ePetite and Recurve SQ Mod. As for attys, I have no idea how many I have but I use 2 Kennedy 25's, Kennedy 24, QP Designs Kali and Juggerknow, OBS Engine 2, Pharaoh RTA and Drop Solo and Recurve for squonking.
It took some trial and error but am now very happy with the above setups so hopefully 2019 will be a bit easier on my bank balance. The only other thing I would like to pick up is a nice 22mm dripper but I'm in no rush for that.
