I love the way these things fly.
That being said, I got to say huntmup that your case is convincing...
I took a spud this weekend that I would have bet was a perfect "10" ring shot. Entry was right on the money - he was quartering away. Somehow the arrow altered course and exited further back than the entry. There was massive damage to the one lung that it hit (jellied).
I think that you may be correct however regarding the angle of the blade & the shortness of the point. I think that if they lengthened the tip/point by at least 3/4 of an inch, it would greatly aid in spot-on penetration.
Hate to see a half skinned deer running by with an arrow hanging out of it because the angle of the attack was too steep for the angle on the blade.
Come to think of it - I bet that there is some type of calculation that could be made with regards to proper angle of attack vs. blade sweep angle.
Any mathematicians out there that want to tackle this??
