What are the best shoes?

The last shop that i worked at, before i called it quits, in the automotive repair field, we had some "old school" equipment that would "arch" the brake shoes to the brake drum diameter after machining them.
That way full contact will the full diameter after how may thousandths of an inch were machined off the drum.
Won't find equipment like that anymore at a repair shop, unless they're really old school, and have the space to keep, and use the old equipment.
