After three weeks I can consistently wrap a .8 ohm wire set-up on my Igo-w3 RBA, but I use the ohm checker, which you can find for under $20 as a safety precaution. The thing about going to RBA from Ego is now I hate how hard I have to hit my Protank Mini 2 to get a satisfying vape. Here's the deal from a relative newb: I went with a mech mod because I like to fiddle, and chill with others who like to tweak things. I also like the assembling and reassembling for various batteries, short tube for work (discrete) and full-length for at home. I like the feeling of mastering the RBA technique. Also, there's a kind of cachet to mech mod usage that I like.
In any case I hope to drill bigger holes in my Mini Protank to try to get that airflow I like. Maybe I'll end up going back to ego!
