I used 32 gauge around a 1/16 drill bit. Not sure how many time I wrapped it but it was more than six, maybe 8 wraps? I didnt leave it in the bit when i torched it, I took it out, pinched it together with tweezers while holding the wires the proper direction, then torched it. Worked fine. What I did, and what most people do with micro coil builds (by my understanding) is to then pull your cotton through the coils while they're installed on the head/atty/whatever you want to call it. Trim the cotton, then lay a flavor cotton wick over the coil wick.
Works like a dang charm on the protank! My build came out 3.7 ohms. I like higher ohms, but wasn't quite expecting that high. Still vapes incredible compared to stock protank coils. I put my provari all the way up at 5.5 volts and its nice.
To the OP, my opinion is to maybe not bother with a dedicated ohm checker. I only have my provari to check my ohms and its probably as accurate as anything out there. only problem is it burns it at a very low voltage while checking the ohms, not sure if ohm checkers do that or not. The SVD should be fine for checking your ohms, that's just me though.
Also, the 30 ga wire should still work fine with a 1/16 drill bit. pick one up at home depot for a couple bucks, or just do like I did and use a cue tip and remove the coil before torching it. Should do ya just fine. Drill bit is certainly nice for the rigidity and you can really get a tight wrap on it
Lastly, on a micro coil, the wires will ALL be touching each other and should be real nice and tight. I feel like it would be much more difficult to pull the cotton through on a non micro coil build
