Had the RPS sport with a disk, then with a puck. The High-5 pedal effort is much lighter, was almost disturbing the first time out. I love it. With the lighter pedal, I have no problem with the short engagement for normal driving. I also have had no "clunking" or any other abnormal noises. No noticeable added vibration either.
