I am not sure that Id bet the ranch on the fact that a hooter shooter would place every arrow from a single at the exact same spot. A friend of mine owned a hooter shooter and he shot my dually through it. The first three arrows robin hooded and he said hed never put a dually in that machine again...just one instance that I have seen, take it for what it is worth. But just think about it. A dually, or a binary, really does have level nock travel. End of story. When tuned, how does it get better? Which leads me to our deate...how does a single, with out level nock travel, ever get tune like a dually? Anyway.....sorry to hear that you got rid of your dual cam.
