Len, I usually don't get the thumb hanging out but if you get tired and let it wander, it will get hit. I've tried several ways of setting the rest. I adjusted the cable attachment 3.5 inches below the roller guard as instructed in the video. I have played with the rod and still see the torque. The tech at Muzzy said they were aware of these issues. If you have found a fix, I'm sure they would love to hear from you as they said they were trying to come up with a fix. Don
