Sinitro, good info. My take on this is to use a matched coil/ballast combo preferably an E coil & maybe one (FBO?) that I believe needs no ballast to get a hot of spark with however much decreased longevity your comfortable w (more power=less life) and a $15 parts house 4 pin ECU to switch it tho the ECU is just a switch it can only switch so much current on/off just like the points it replaced
live every 24 hour block of time like it's your last day on earth

 this pretty much where i'm at right now except i don't know why the OP boiled his coil when he had the matched BR and coil. and why is the voltage/current ok for my MSD ECU without a BR but not ok for a MP ECU?

As mentioned previously..
The MSD box has a 20 degree window for its multiple firing vs. the single firing (0 degree window) of the Mopar box..
The multiple firing puts a higher voltage/current draw on the coil... Also the ballast resistor is more for limiting the current rather than voltage to the coil.
In the earlier days coils, boxes these could not handle as much voltage/current as the later available components..
Just my $0.02..

OMG - it clicked! in reality i'm 'lowering' the ability of my MSD box and coil by using the BR.........

Sinitro your 2 cents is really adding up & making me nervous!
Im driving 3 hrs to Carlisle in a few days. I had to recently abandon my FBO A688 ign set up because my module crapped out & let me coast to the side of the road. Hooking up my spare module I carry with me with a ground strap started the car. After this test I wanted to mount the spare module to get home. Mounting it & trying to restart didnt work....now I again had no spark! Took out my spare coil & it fire up & got me home with the spare coil & module.
Got home & retried FBO module....no start. Tried FBO coil again...starts every time.
In closing I now am running my original chrome box with a new Blaster II coil & the supplied .8v ballast (also same ballast supplied with the FBO kit)
In your opinion will this current setup leave me on the side of the road going to Carlisle????

Don't U have AAA... 
Running the other ballast resistor is fine...
You may be missing a few KV of spark but the Mopar will run fine..
As I posted previously I like the traditional Mopar setup but prefer the Chrome box vs. the Orange box. The later Orange boxes seem to fail frequently probably due to Mopar sourcing from Nanking... 
Just my $0.02...
