That peach-on-peach combo sounds killer, using the rub and then doubling down with the Kosmos glaze is definitely the way to go for maximum flavor. I haven't fired up my pellet grill in a few months either, but there's honestly nothing like that first smell of smoke hitting the air to get you back in the zone. If you’re going for that sticky finish for your mom, I’d lean toward the Blues Hog; it usually tacks up beautifully on baby backs compared to Kinders. Looking forward to seeing how the bark turns out!
