Clutch Master Cylinder

Thinking of changing this to a different size. Any feedback from anybody who has fitted one would help as would the best size.

I did a search and it was Wayne that did this. He mentions the standard master cylinder bore as 3/4 (19.1mm) and has gone to 5/8 (15.9mm). I wonder what others have done as you can also get 7/10 (17.8mm) which looks like an ideal halfway which would reduce some of the pressure without reducing the travel of the slave that much.
