Just curious to see if anybody has tried it.Im starting to get into the RBA world because of the insane amount of vapor you can get off it and learning how to make my own coil. I'm tight on money and all i have right now is an ego twist, i love my pro tank but im not satisfied with the vapor production is gives(ive compared both the 2.2 ohm and 1.8 ohm heads). i was thinking of getting a smok RDA (because its cheap and ive seen some people getting loads of vapor off it) and re doing the coil and wick to see if i can get some nice clouds off it. i have yet to see anybody with a RBA on an ego. do yall think its worth it or just wait untill i have enough money for a K101 and a smok RDA(im gunna mod it of course). I don't know, just a thought if a mod puts out around 3.7v and so can an ego, why cant you get nice clouds off an ego? or am i missing something? Ill appreciate all the help i can get!
