Yup, very good flight. I'm thinking thoughit may be thevented four blade. I don't know ifif it has anything to do with anything,but I shotarrowtipped with the same setupinto a real decent compressed bail. When I pulled the arrow out, it was very tough and I had about a fist full size of hay sticking from the vents all intertangled. Make you wonder about vented blades. Anyway, I got the penetration I needed on the three deer, just none of the arrows were laying on the ground after the shot.

And I agree that things do happen sometimes.
