You also didn't say what kind of bow you were shooting or what length quik spin vanes.
The shorter (2") vanes have a higher profile then the 4". I was having flight issues with my PSE DNA bow with 2" Blazers which have the same profile as the 2" Quik Spins. The vanes were making contact with the riser. I don't know why but PSE IMO does not put enough center shot clearance into their risers. I switched to the 4" vanes and have no issues.
