The recommendations I've been reading would suggest you should do a water-only flush and switch to ELC, your cooler is good and they're worried about clogging it.
If you did clog it, you could try the backflush routine to recover it. It seems that you would be a good candidate for this to work if your flush is what caused your clog, since it hasn't sat there and cooked in for miles and years.
I started with a high delta 45° so I had nothing to lose by trying the backflush, and I got the delta down to 15°. And I'm pretty sure mine HAD been that way for a long time. So if your truck was mine I'd do the chemical flushes and backflush and see what that did, but I'm wary of suggesting it for you. I'd at least suggest you read the threads about it, search for JFirstFord.
I worry about the guys who just flush out the Ford coolant with water. They are still going to have the crap in there, that they were afraid of getting in their oil cooler, and I think it's just going to happen over time anyway and they're still going to get clogged oil coolers even with the ELC. I say go ahead and get it clean, and if it clogs the cooler, change it. Now you have a clean system and coolant that won't make it worse, add a filter, you should not have a clogging oil cooler problem any longer.
