Just a thought : a rebuild kit is a lot cheaper and if the original bore is
in good shape, just as good as a new one.

It's actually a common retrofit, to band-aid "not enough travel" problems.

Normally, the larger MC would make the pedal heavier (though not enough to
be objectionable, IMO, unless there's something wrong with your left leg).
However, the hydraulic TOB is supposedly lighter than the stock setup, so
the end result would probably be about the same.

Info on how to avoid over-stroking the hydraulic TOB should be included in
Herman's instructions.  Necessary even with the .70 MC.
