I use a 10 gallon cooler/braided hose..the only time I had a stuck sparge is when I had a 24# grain bill. It squished the braided hose and didn't allow liquid to flow through it. I had to blow into the tubing attached to my mash tun to unstick my sparge. I currently have a bazooka screen on the way to try to avoid that problem. The only time I would ever consider rice hulls is with a wheat beer.
