I am by NO means experienced with RBAs or rebuilding coils. I have rebuilt 2 Vivi Nova heads (2.0 ohms; 1.4ohms) and I was Piffed a Vision Eternity! I love to drip so I was intrigued by the VE's drip mode.
I tried, and tried, and TRIED, to use the replacement coils that came with my RBA but it drove me nuts!

The wire was so small and the wick kept coming apart. I contacted the person who Piffed me the VE. They were just so generous! They included wick and wire with the VE! It seemed like it was the same silica wick and 32 gauge Kanthal wire I was using to make the Vivi heads. I was confused!
Everything I turned up in pre-coil building research for the VE said that 32 ga. was too big to use? Research also implies that the size of the silica wick I was using (unsure of gauge but it was larger than what comes with the kit) was undesireable as well so I asked my Piffer. They said they used 32 ga wire all the time. So.....the first head I built for the VE I made just exactly like I would for a Vivi. It came in at 2.0 ohms. It is not pretty. It does, however work great!
I've been using the same head on the VE in drip mode for about 1.5 weeks. I love it. The original specs say the VE will hold 35 or 40 drops (2.5-3ml) of e-liquid. Then I saw reports about people having leakage problems. The most I have ever put in my VE in drip mode is 25 drops. It works like a champ and I get good flavor without leakage. If it starts getting a burned taste i disassemble it, wash it out with hot tap water, put the coil on an old 510 battery and burn it off.
My experience, as a beginner and one who loves to drip, has been positive with the Vision Eternity in drip mode.
