Some guys have been able to get good clearance with the qad, but I am not one of them....neither is a good friend of mine that knows more than most people forget about tuning. I am a decent tuner, but not as good as him. My problem started with the rest on a pro 40 dually. No matter what I did, I could not get clearance, every time. Called QAD and spoke to charles at length. THis was the summer of 04. He said that I needed to send it back for a stronger spring. Great customer service. Changed the spring and still had contact issues, though not as much. I went back to the trophy taker that I used to shoot and have no problems. My buddy went to a rip cord and has had no problems. I accept that people can get this rest to work, but I also think that there are some people that have more contact than they think. SO, I have a strong spring QAD sitting in the garage....
