Anybody have any ideas for the best sub-ohm coil? I've tried several different cool setups, but none are below .2-.3. Any ideas?
Cool builds?

Keep things simple. Use thicker wire and/or less wraps. If you don't have any thick wire (24 gauge or so), try twisted wire. You could also go with a smaller diameter coil, but in my experience once you get down below 0.3 ohms you need at least a 1.5 - 2.0 mm diameter coil in order for the wick to bring the juice to the coil fast enough.
There really isn't any 'best' coil. It's like asking what is the best car, or the best meal. Tell us a bit about what you've tried, what you liked and where you want to go next. That will really help.
Okay. Best build for a microcoil. I've tried several times, a dual coil setup. Wrapped around paperclips, screwdrivers, etc. I've used 20g with 4/5 wraps and still not where I'd like it to be. Are there any ways of improving your techniques besides buying 100ft and practicing?
Dual coil, 5 wraps around a paperclip, with 20 gauge wire should be taking you way, way down below 0.2 ohms. My 24-gauge dual coil, 8 wraps around a 2 mm rod puts me at around 0.3 ohms, and that's even with the fairly long legs needed for good airflow on my TOBH.
This has to be way below safe limits! You need to make the diameter bigger, or use plenty more wraps than that.. but then it may not heat up fast. So i would go w/ a bigger diameter.. do you have a legit ohm meter?
My love- Kawa green Reo grand LP w/ TRA Super light door, with TOBH and chuff top!
or if you want to keep it heating up fast but but slow down the speed at which the juice get's vapourised then opening up the wraps from contact to non-contact will help a little or/and taking shorter hits (1 second blasts)work very good for me and keeps the atty cooler than say for example a build at maybe 1.0Ω where you might hold the fire button for about six second's

Clean! I like it. Just yesterday, I built a braided coil out of 30 gauge. I braided 3 strands of wire together and made a pair of 6" strands. Wrapped each one 8 times around a 2.5mm drill bit and it came out .39 ohms.
Typically I build my BF Trident V2 with a 26 gauge sleeper build, 7 wraps for .37 ohms. One of my long time favorites. The 30 gauge braided build takes a while to heat up and takes a couple draws to really start chucking the vapor, but once it's heated up, it's the most vapor production out of my stock Trident I've ever had, and the Trident is nowhere near a super high performance rda these days. It throws fairly competitive clouds being on a Reo though, once you factor voltage drop on a Reo vs a traditional mech. I may try another braided build with 32 gauge and do maybe 5 or 6 wraps instead of 8 wraps. I think that'll spool up alot faster. This 8 wrap coil is fairly large. Here it is
Doesn't look super clean but it works really well. I used alot more cotton than I normally do, because I wanted it to expand and make better contact with more of the wires. I was really worried about having parts of the coil glowing orange under normal use being a braided coil, but it works impressively well. I'm usually not one for exotic builds, my dual 26 gauge sleepers are usually plenty for me, and I never really dip below .32 ohms, because the Reo has so much voltage drop you don't really benefit from builds a whole lot lower than that
Parallel coils are a great way to drop the resistance of your coils without having to buy lower gauge wire. Also, using a smaller ID will significantly effect your resistance.
As far as "best build"... My personal favorite is a 5 wrap dual parallel coil, one strand 24g and the other strand twisted 26g. Gives great flavor with good vapor production
