I desginate one as my practice head, the rest are hunting heads...I also buy an extra pack of replacement blades, never did like even practicing with "practice" blades...

I also shoot every arrow that I wll hunt with at least 3 times with this blade, then put on a new one and it goes into the quiver...
Once I shoot a deer, that arrow is checked and refleched and it then becomes a practice arrow if it shoots well...
