FWIW, I installed the PIM McLeod clutch, pressure plate and throw out bearing system in 2017. It was MUCH stiffer than the old, slipping, non-Pantera clutch I replaced, but the stiffness of the new clutch was never intermittent. So, I installed an Effort Reduction Kit a few months later, and the difference was noticeable. It was either that, or I was going to have to go to the gym to build up the strength of my left leg.
