I was under the impression that Sony VTC4s are 30A, which is what I see them listed as. Is that wrong?

Davidos, which VTC battery and where did you get it? VTC5s will most likely be a fake, they haven't been made in a long time and it seems everyone has run out of old stock. The Sony VTCs get cloned, so it's best to get them from a recommended vendor like Illumn.com. For an Ohm meter I would recommend USA Ohm Meter. There are cheaper ones out there but these are the best IMO and are highly regarded.
Its a VTC4 I purchased from my local cape shop is a 30a

So Do a 30g build? A 30g build 7 wrap quad coil or dual coil?

I thought both existed -- 30A versions with less mAh, 20A versions with more. But looking at it now I'm kind of blowing my own mind. I thought I had 20A VTC4's for the longest time, but I guess they're actually 30A? Hm. Still, I wouldn't push any battery past 20A. That's such an excessive amount of power. 10A is like, 100x more than enough to kill a man.

Also, quad coil? Why? You'd be better off with a large surface-area dual coil. Not to mention fitting a quad coil into a Patriot is gonna be a nightmare, lol.

Which would burn faster 30g 5wrap or a 28g 7 wrap

Gonna assume it's a VTC4, 20A battery (probably a safe assumption).

At that resistance, the lowest you could theoretically build is .22 ohms. With a fully charged battery, this would put you RIGHT at your amperage limit. You don't want to be at the limit. It's a good idea to allow at least 30-50% headroom to allow variances in the battery/coil/other random factors that you can't exactly control. You can plug the numbers into Steam Engine to figure out what resistances produce what amperage. For example, you can plug in the voltage of your fully charged battery (4.2V) and the resistance of your coil. Steam-Engine will tell you what amperage that's producing, and what wattage that's producing. You can switch the variables around -- the calculator is very dynamic.

Your limit is 20A, but I would suggest keeping it lower than 13A -- that's a metric "****load" of power man.

nyiddle linked it already -- you can get it for your phone too...
