I'm not ricks but for a beginner, keep it simple. Kanthal 28g, 8 wraps (coils) and cotton balls (organic from a drug store).
There's a bunch of how-to videos on youtube for the kayfun 3.1, KFL+, KFv4, etc that are all pretty much similar to a KM3 build. Most of the techniques apply since the build deck is similar across all of them. Just search for "kayfun build".
This is a good site to figure out what your coil should be reading when it's on your atomizer and mod:

Thank you for your response, KTMRider. Greatly appreciated - I'm trying to glean as much info as I can - so far it seems most people are advising me to keep it simple, like you, so that is what I'm going to do. There seems to be so many variables which makes it confusing. For the most part, I just want to make sure I know what I'm doing and that it is safe.
