Curious as to why you chose a finger/Long style pressure plate as opposed to a diaphragm/Borg & Beck style. My experience has been that the Long clutch is more difficult to feather/slip than the B & B is. The Long clutch will take more abuse and run a little cooler as a result.

Back in the day, cars doled out for members of the press to drive and evaluate routinely had Long clutches installed, regardless of what was put in the regular production vehicle. Usually if a heavy duty clutch could be ordered, it was a Long clutch.

If the car is to be a daily driver, I recommend the B & B. FWIW: I tend to be easy on clutch disks.
