    79-0064-1 is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Professionally installed. Tech said he had trouble I've only used the gear for a short, "run in" period but found that it runs very quietly and seems very smooth. "Hard launches" are next and I hope it holds the torque I will be applying.
