They aren't kicking right, I don't think. What you are seeing is the vertical component of the flight when you cant the bow. In other words, with the bow canted, the arrow comes off the shelf slightly nock-high, but this appears to be nock right with a canted bow. That's why you need to bareshaft with the bow pretty well straight up and down. I think Morrison recommends this on his website. However, I can't believe those arrows aren't underspined at that weight with that much up front. Paul.
