RE: QAD issues
Dave is 100% right, you must move the cable clamp down. I have the General, and mines down near the grip area. Also make sure you have the correct launcher arm on your QAD. You need the TL1 launcher arm. Its specifically designed for Binary cam bows.
If you done all this, and still got contact. My only other ideas are make sure the rest is moved as far forward to the bow shelf w/o actually contacting it as possible. That will give a little more time for vane clearance. You can also try rotating the arm mechanism a little, as long as it also doesn't contact the shelf when it drops.
Beyond that my only other thought is the higher profile blazer vanesbe the culprit.
