I've been in here for quite awhile and haven't upgraded my kit despite contemplating for a Long while. The main consideration is the difference between vaping and analog. I'm vaping at 0.4ohm 46w on a 6mg juice w my Subox and lung inhaling instead of mouth to lung (analog style), no doubt vapor production is good( not like those cloud chasers but significantly denser clouds) it just isn't satisfying. Honestly idk what I'm missing out and I'm definitely not incline to drop $200 on a brand new mod and rda to only find out there is still a significant difference from analog. Initially peipple say its juice issue but even after trying US 6mg, yes it's better than msia/home brewed, but still lackluster. Definitely would love some help here... I'm aiming for a rx200s or 2/3 w a rda for maximum kick.
