I'm sorry you didn't find that helpful my friend.

If you are convinced that this is an issue regarding non-planing shapes or surfaces; Jim Thomerson provided a solution. As you may know, mechanical broadheads retract and spring open and lock on impact. These are already commercially available and are actively marketed to people that share your view of the problem. You are not the first, you won't be the last.

If you are willing, however, to entertain that this may not have anything to do with non-planing shapes then please look to bow tuning.

Have a nice night and good luck in the woods!

Tom
