After 3 hours of fiddling (inclusive of taking pics, cooking and eating a chicken pot pie and taking a 30 min phone call), I have #1 eGrip RBA cleaned, recoiled with a Joyetech factory coil, rewicked, and vapin sweet n airy. Man, what a difference. I'm going to use 10 days on a wick / coil for a benchmark with the juice I like (again, the Dekang USA Mix VG 16 mg and the Basic Tobeecco VG (< 2% PG) 12 mg mixed 50/50). That might change based on the dry burn experience below, and as I have a go at #2 eGrip after this post.
This afternoon I swang by the Cignot near me and picked up the Eleaf ohm meter, the RBA 510 adapter, and some juice from my man Dennis and got to meet the delightful Vicky - quality peeps.
Funny though: I was getting ohm readings all over the map, but finally got 1.5 a few times in a row after priming / assembling and stopped futzing and installed the RBA in the body, which is firing no problem. Two suspects:
1) I think I needed a $2 adapter to go between the eGo threaded posts on the Eleaf meter and the Joyetech 510 RBA adapter (which threads fine into the eGo twist I used to fire the new coil, which worked just fine - except for oddness which I'll relate below as well). There's a thread adapter / connector that comes with the Eleaf that the instructions say is to go between the eGo threads on the meter and 510-threaded devices. I had to futz with this a lot, but I was able to get readings (though not consistent).
Dennis had mentioned this adapter (forgot who makes it, but it's not the Joyetech eGrip 510 adapter) - but we got to talking Vape World (specifically the most recent bogus formaldehyde "study"), then a customer came in, then Vicky arrived, and I had already closed the sale and split to let Vicky do her business.
2) One of the tiny deck screws is definitely stripped - more than once, I was getting 2-3 ohm readings, and would just try to tighten the screw while in the 510 adapter on the meter, and it would go back down instantly.
So here we go:
Here's what the factory-installed coil at 14 days, and wick job I did about 10 days ago (mentioned way back in this thread) looked like:


Grody! Grody to the max, I'm sure! 
But honestly, this didn't taste bad at all - I was only doing this cuz I was curious, and reading accounts of folks only getting a week out of a factory RBA coil vs. others going two weeks (which this one was at). Resistance: 2.93 with the wick, 3.94 after I pulled the wick (but this might be due to the meter post / connector / adapter fiddling / weirdness). Fellow noobs / noobettes take note: this has all the world to do with your juice. Unflavored PG will not gunk up a coil for a long time, where a Belgian Waffle VG will do it within hours (if I understand this right).
Here it is before and after 4 or 5 7-10 second dry burns on my eGo Twist at 3.2 V (now I don't feel so bad about this guy, he has a use after all lol):

Resistance: 1.54. This very easily could be rewicked and used again for the tight of purse strings.
Here it is after I pulled the RBA completely apart, cleaned it, and installed a new factory wound coil:
Resistance: 1.54. However, with all the fiddling, I was seeing as high as 3.3, and low as 1.4.
I think it's only 5 attachments per post - more to come for #1:
