Master cylinder bore size

What size bore would you guy's run? I'm looking to get Wilwood pedals if I can find the $$ to switch over to a clutch, and they have several different bore sizes for the brake master cylinder and clutch master cylinder. At first I figured to get the biggest they offered, but read on there site that to big of a bore can cause a hard pedal.
Keep in mind I'm only have brakes on the front axle.

They offer 3/4, 7/8 and 1 inch bores for the brakes, and .625, .700 and .750 for the clutch.

Alan.
You asked about my dual slave set-up. All you do is use there brake petal witch has the mounts on it for dual resivor. and run your lines to the slaves. Now to mount the slaves to either your fork or in my case the cross shaft you need to make a custom braket to mount too. Its really not that hard ther are probably 4 to 5 trucks up here now that have it already. As far as the bore gos I personnally would run a 3/4 or a 7/8 bore on the slave and the same on the resivor. Some guys will tell you to run a bigger slave than resivor to prevent the o rings from blowing out, but you dont have to.

Your going to run their dual master cylinder brake pedal ass'y and run 2 slave cylinders!
Please elaborate on this, as I plan to run a crossshaft setup as well. Is one slave not enough for a dual disk?

We have run the Wilwood single cylder master cylinder clutch pedal combo (1 inch. Bore) and the Wilwood pull type slave cylinder on a 2 disc clutch for quite a while now. I mounted the bracket for the slave on the transmission and made a mount for the slave to mount to the clutch Fork. My only issue has been with the pressure plate rubbing the clutch fork. A little Grinder work solved that issue. Love the set-up it is so much better than the old manual linkage.
