Well, I didn't make myself sick ...yet.
After soaking my loin pieces twice for a total of about 36 hours to reduce salt content, dried overnight then smoked with pecan wood Friday for a total of nearly 6 hours to get the IT up to 153°.
I bagged the four pieces and chilled until last night, (as long as I could stand it), to let everything equalize, sliced up one of the chunks and gently re-warmed it while the skillet was still hot after scrambling my eggs. Except for still being a bit salty for my taste, it tasted like cured pork. Now I have to buy a package of commercial CB because I can't remember what it tastes like for comparison. I'm liking it!
As to my original question, I finally got around to starting to read Charcuterie by Michael Rhulman & Brian Polcyn and each time they give a brine recipe the directions say to bring the ingredients to a simmer, including the curing salts.
Tomorrow after work the butt in the 'fridge begins it's transformation to BBB. Stay tuned.
