What cables and crimps did you end up with?

Followed the recommendation of @AKNick and went with the Steelon nylon coated wire @ 120 lb:

Crimps are pretty nice aren't they? I think I used 80# on the timber pull pull wires and all my 30cc stuff... the 120# must be really nice stuff. Sometimes you can downsize the crimp to get a tighter tolerance.

Don't think you will stretch that cable.

Guess I need to run a few numbers. I may have assumed 120 lbs would be sufficient, and have a margin of safety.
Breaking out the calculator now.

600 In Oz servo with a 4" double arm will result in less than 20 pounds tension. You have plenty of safety factor.

Good grief! The rudder servo in this thing is 425 oz and the arm is 2”. Plenty is an understatement.

Almost a factor of 10! That's elevator cable safety factor range.

The magic formula for cleaning models! If it’s good enough for Air Force One, then perhaps it will do in a rush for Python 100.
Seriously, I’ve used these products for years and had given away my last bottle to a young man to take care of a new to him Ford Mustang.
Amazing service, after placing the order on Friday afternoon, it arrived an hour ago.
