For the factory disc/drum setup, a 15/16 to 1 inch bore master cylinder is usually a nice compromise between effort and pedal travel. Most of the aftermarket brake kits mentioned above have less caliper piston area than the factory calipers (6.7 square inches), so they require higher operating pressure to function as intended, thus the smaller bore MC's.
Pad compound can make a huge difference in braking performance/effort as well. Depending on the bore size MC you choose, you can use your pad CoF as well to "tune" the system. I prefer a minimum of a "FF" rated pad which includes most off-the-shelf semi-metallics and excludes most "EE" rated ceramic options. Given a choice between an "FF" and "GG" pad like the Hawk HP Plus or EBC Yellowstuff, I'll take the "GG" pad in a manual application almost every time...a little brake dust never killed anybody...at least not directly.
