Ditto to what David sez regarding the Mcleod hydraulic set up. I have used one in #142 for almost two years, and have no complaints. They have also made some improvements in the newer series, eliminating the banjo fittings, so so much the better.
The key is proper set-up. I found that if you explained to McLeod what you were running, they would build the unit to the proper specs. Mine happens to be 3". If you go with one, you will love the clutch feel....just remember to install a pedal stop.
