Looks good for sure. No sharing a recipe is lame. I could understand if he ever had a plan to sell it or have it a his restaurant or something in those lines. I have a ton of family recipes and anyone's always welcome to them if the ask nice.
I use SBR sauce. Just like spaghetti sauce just add to it. I add apple cider vinegar, chili garlic paste, a splash of fish sauce, and some red pepper flake. And that's the sauce I use on my ribs on top of different rubs. Ive had lots of compliments.
