I'm amazed at Denny's 300+ brews with a dinky little ss braid hose--it baffles me how it works so well with batch sparging (i.e., "just open the valves and drain it"). But, I'm still a believer in batch sparging
I have a SS Bazooka braid (12-inch) in an {orange} round 10 gallon cooler (and, yes, I do 10 gallon batches). Haven't really experienced a quick lauter yet (but, to be fair, I have had the barleycrusher maltmill on an extremely fine crush--narrow mill gap). My efficiencies have been good, but my lauters have not been quick, let's just say.
My last brew was an american wheat.... the lauter from hell.
I've since set my mill gap back to "normal." I'm still undecided about the SS Bazooka braid. My next brew day is likely next week.
