This is what I'm thinking, I already purchased 5 extra coils per tank. I'm still using the ones that the tanks have included. However I will not throw any of them away. Rebuilding just might be on the horizon.
A coil lasts from a week to a month. And sometimes you get a dud.
Soak the coil in hot water every 3 or 4 tanks or as needed. Some juices clog the coils more then others.
I only use the Protank 2 mini. I can make them work great for me. They might suck relative to a different tank, but I can make them consistantly suck and I am happy.
I am unsure if the "burning" the coil to remove the gunk trick ever works for me. By the time I try it, the coil never becomes "brand new" again. It is just the beginning of the end.
In two months, I think I got 2 finished coils (saved for the future). I keep 3 tanks full so I can switch flavors.

Your supplies sound good. I would suggest that you find 4 or 5 flavors that you like and you will be set for years. I like (Cinnamon Roll, Moo Juice and Orange Dream Bar from Mt Bakor Vapor).
After a short time, I went the Vamo V5 route and re-chargable batteries (18350's and 18650's). So I bring the Vamo and a couple extra batteries and a few twists and 3 full tanks and 15 ml of more Cinnamon Roll, and I can easily last all day (or a week).
The Vamo was like $32 and the batteries are $5-10 each. The charger (Nitecore Intellicharger) is less then $20.
I got the iTaste MVP v2 and it is nice, but when the rechargable battery dies the unit is done. It is a good deal for something in the $40 range and it came with 2 tanks that I never use.
So nail down your juices (it could all be illegal or taxed at 100% before you know it).
Christmas is coming. Maybe Santa has a Provari for you? He is crazy like that.
