If you go with the BA hub you may need to change the front brake master cylinder. The BA is a single disc and the speedmaster is dual....The speedmaster may be too "grabby" (larger piston for the dual) for the single disc. I do not know for sure. Also to clean things up you would want to "shave" the fork leg with out the caliper.

I don't know if these are gone six post down:
