Maybe you dodged a bullet, maybe not. I batch sparge and use a braid, but I have had a few stuck sparges. Mainly with rye. I made a 6 gal batch of roggenbier with around 60% rye and even with a pound of rice hulls, it still took almost 2 hours for the runoff. It's cheap insurance considering how much of a PITA a stuck sparge is. I at least have grain bags from my previous BIAB batches that I can use if I get a stuck mash.
