5's my #.

Four with broadheads and one field point. Why so many w/ broadheads?
Because of what Ausie-guy mentioned- PIGS. They usually (except big boars) run in packs and don't run very far once one has been hit.

I carry the fieldpoint arrow because at the end of every morning hunt I like to pick out a small object on the ground to shoot at (leave, ant mound etc.) to make sure I'm still on. This keeps the confidence up when you nail it everytime!
