I needed to reduce the length of clutch pedal travel in mine and went from a 3/4 inch master to a 7/8 master. That 1/8 inch increased bore did shorten the throw enough to be noticeable - however, I didn't really notice a corresponding increase in pedal effort.

So, I sort of suspect that if you go to a 1/8 inch smaller master that you won't notice a lot of difference in pedal effort but the length of pedal throw will be more than you want to live with.

I think if you really need to lower your pedal pressure the two most practical ways are with a twin-disc clutch (expensive) or a hydraulic throw out bearing (a controversial move).

For what it's worth, I thought my pedal pressure was very heavy as I was assembling my car - but once I got to start driving it I got used to it very quickly or maybe it even lightened up very slightly as everything got cycled in a few times.
