Get the Stallion, ditch the BB7s and replace them with Spyres with good pads and two piece discs. Spyres from Aliexpress and the TR-033 discs from wherever is cheaper. Ditch the pads that come with the calipers and get some good ones. Worthwhile rebuilding them straight away with a sparing amount of high temp brake caliper grease, they'll then work pretty well for years.
