I remember reading somewhere that mechanical broadheads may be effected by this mesh. I don't use mechanicals but has anyone had a problem?

Velcro holds the mesh in place. This is great because it is replacable. As a side note we have a black perminate marker in the blind forrecording kills. We point at the hole with an arrow and write the name, date, species and time of each kill. It is kind of a fun record.
