The late bays use a 24mm dual circuit MC. The pedal ratio of an early bus allows the use of a larger MC without drastically increasing the pedal effort. A bug has less pedal ratio and hence you need more pedal effort.
For the record, I've got a 4 corner C2 (1991) setup on my 65 bus with a early 944 stepped MC (23/19), and I'm heavily leaning towards and early 911 (20.6mm) MC to increase line pressure and decrease pedal effort. Although I do admit that my pedal is very reasonable and it's doesn't take much foot to make it stop, but I'm sure it can be better.
