I have heard two different things when it comes to this. Some people say that you should have at least one blade line up with your cock vane. Others say that as long as your arrow is true(spin tested) and bow is tuned. It does not matter at all. Currently, my broadheads are just stuck on my arrows and they fly great. I shoot them up to about 40yds with no problem. Good Luck
It doesn't matter how the blades line up as long as they spin true. With offset or helical vanes,feathers, the blades aren't cutting the same air as the feathers are anyway so why should it matter.
