When shopping for replacement pads for the Wilwood brakes on my Pantera (which is a dual-purpose fast road/track day car), I phoned Wilwood and spoke with their tech reps, who also made the same recommendation. The BP10 is very linear and constant regardless of pad temperature. The BP20 has an ever-increasing coefficient of friction as pad temperature rises, and the max operating temperature is higher as well.
I elected to go with the BP20 for this reason, and have been extremely happy with them. They do generate rather more dust than I wanted (I was replacing ancient Wilwood 'green' pads which were enormously dusty) but they do work quite well.
Wilwood pads are actually manufactured by Raybestos, by the way.
On my 427 Cobra (with Wilwoods in the front) I went with Hawk HP+ pads, which are similarly excellent.
