Sorry for bumping a kind of old thread, but I joined this site because of it and was hoping the OP was still around to answer a few questions and give me a little feedback. I'm using a dual coil RDA. I read this thread and immediately tried a build with the steel cable. First off, I bought galvanized steel cable from the hardware store, not stainless. Don't use that stuff because it tastes god awful and is probably has toxic levels of zinc. I could be wrong on this one but I abandoned the cable build, which was 1/16 cable, a wrap of 400 mesh SS cloth, and 4 wraps of 30 gauge kanthal. Right now, I have a VV/VW mod (my mechanical is in the mail), that will fire down to .8 ohms. I had really good results with it using a 3mm silica wick wrapped in SS mesh with 5 wraps of 30 gauge Kanthal. I was able to vaporize my BHO and get great hits. It doesn't quite compare to hitting a nail, though. My questions for the OP are: Do I really need your setup to get hits on par with hitting a nail? I don't want to invest any more money in this stuff, especially batteries. Will I be able to get nail-like effects with my IMR batteries, 28 gauge Kanthal, and silica and SS mesh? Last but not least, what are your thoughts on using the galvanized steel cable? Do you think zinc toxicity is a possible issue? Thanks for reading this and sorry for bumping a month old thread.
