Here are some links as promised. These 3 things will replace a Darwin and Provari for you battery and atomizer testing.
This one you screw on any atomizer and see the resistance. Might need an adaptor for old school 801, but the rest are covered. I like this because you don't have to fire the atomizer to check ohms like some devices.
Carto-Mizer Atomizer tester
This is new, and if you have ever had multi-meter leads slipping on the end of a battery this is great. Check your battery voltage. You don't want to use a battery past about 3.6v of charge, and this helps you find that data quickly in a smaller to carry package.
Battery Tester
Bottle Battery Tester
This load tester is awesome, and I have been using a similar one for a year and a half, and it's all in one piece. I would suggest getting a long at least 1 inch 510 extension to make it easier to screw into deep cups on REO's.
Load Tester
If you want to run 1.2-1.4 ohm atomizers on a grand with rebuildables you might be exceeding the wattage out put of a typical AW IMR Battery. MNKI makes a battery (18650) with a higher watt limit, but it's not button top, and the REO plays best with button top.
IMO you have an amazing mod there, but you might be exceeding it's limit?
