Resurrectors are 1.7 XL Smoketech single coiled cartos which give a warmer vape and better TH. They're one of my favorite cartos. Although I also use several other atties as well: Joye 510, Cisco LR 2.0 & 1.5 306's, and IKV 1.8 i06's. Have no problem using one or the other.
You shouldn't have any issues with vaping 100% VG juices. Although you do have to let it settle for a few minutes so the "diapers" of the carto have been properly soaked. Otherwise, you'll be having wicking issues that will lead to burning.
306 atomizers have the same threads as a 510 and will work for all 510 devices. The differences are apparent since it doesn't sit in it's "cone" and so, you'll need a 306 drip tip. The i06 atomizers are like the 306 in looks but it is bigger and basically everything else has been redesigned and works differently than the traditional 306 since it has a larger bridge and catch cup in the interior.
And yes, you CAN get better life from clean them properly. Although, atomizers a 1.5 ohm Cisco atty will have a slight learning curve that can be prove to be an expensive lesson to be learned. However, you can get some 510's which are more forgiving and easier to learn than others. Once you get comfortable with these than Cisco 2.0 and 1.8's are likely to be the next best step.
As for Fluxomizers, they are basically another type of clearomizer or CE 3. Which is a non-filler cartomizers that does take some modifications to make it work at an optimal level. This is due to some complaints that they have leaking problems as well as decreased flavor. Also, they have a higher ohm than some carto's and atty's (2.4 +) which might not perform that great for 3.7V. Honestly, I haven't used those myself and I can't tell you if they would work for a REO. All in all, if you don't like messing with stuff then this might not be the best choice for you.
Hope that helps.
