I've been searching online for a good explanation, but have yet to find one. How does the size of your coil winds actually affect your ohms/heat/coil heat-up-time ?

The difference would be in the wicking, and how quickly the juice can be "transported" to the coil(s). Therefore, I'm using 2.5 mm or 3 mm IDs for my coils, usually in a 0.3Ohm range.
Bigger coils will have higher resistance, because you'll use more wire to wrap them - 6 wraps of wire around a 3 mm inner diameter would use more wire than 6 wraps of the same wire around a 2 mm ID. You'd need to deliver more power to heat a higher-resistance coil in the same time you'd heat a lower-resistance one.
As others have said, bigger coils are becoming preferred as regulated mods become de rigeur because they allow for better wicking. Also, more surface area on a higher-ohm coil means more space for juice to vaporize.

Thank you so much for your experience and expertise, guys! I love this site!

I think I need bigger coils. I've been using blue screwdrivers to build mine, but I've been having a hard time with wicking lately. Is there something I could use to get 3mm coils?
I've found that I can get the same production and flavor on 3mm coils and 2mm coils running the same resistance, the difference is that 3mm coils are more tolerant if you don't wick them perfectly. I build larger diameter coils simply because I don't always have the time to struggle with the perfect amount of cotton in my smaller diameter builds.
Depending on the tank, I prefer a 2.5mm ID coil. The 3mm coil might restrict the airflow, e. g. in a Kanger Subohm RBA.
