Greg - I'm not too sure the stroke matters a whole lot as long as there is plenty of MC capacity in comparison to the brake caliper displacement - and that is going to vary from brake setup to brake setup. Unlike the clutch MC you shouldn't be fully stroking the brake cylinders or otherwise you could run short on brake pressue and also have no reserve capacity.

I don't think the stroke will have any effect on the pedal pressure as long as you don't run out of MC capacity - I believe the MC piston diameter and caliper piston diameter will most influence pedal pressure.

It's interesting that they recommend a larger MC for the rear brake circuit than for the front one. From what logic I understand on these things, your rear brake calipers must be of larger piston diameter and displacement than the front brakes. Probably has somehing to do the number of pistons in the calipers. More pistons are often smaller diameter.
