RE: cock vane perpendicular to cable?
Spray some desonex foot powder on the last 6" of the arrow and then shoot it. You will know if you have a problem or not when you look at the arrow and bow after this arrow is shot. I do this with all bows shooting blazers at least once because they are such a high profile. This step can save a lot of tuning headaches down the road if done before you start setting it up.
