I just ordered a Crown 3 but can't decide what mod to get to run it on. My current setup is a Wismec RxMini with a Tobeco supertank mini, and a Smok GX350 with an IJOY RDTA 5. I like the idea of the RDTA box mini, but the battery life on the PD270 should be better. Right? What are you guys running and/or prefer to use and why? Any input is appreciated guys.
