I use field points when having fun and just want to shoot. I put on the B-Head when I am ready to go deer hunting. Practicing with b-heads is a must, not a option. Some heads will fly just fine, use them on a different bow or type of arrow and they fly like junk. You need to practice with them to make sure they fly good. Not saying you need to use your heads every time, but at least one practice session with them before your season starts. I have two packs of heads, one pack of three that I shoot all of them and make sure things are ok with that brand of head. Then on the new pack I shoot all the heads a couple of times to make sure they are ok, and then into the quiver until a hunt is where them three arrows stay. Again, you have to do at least one session to make sure they are ok with your set up no matter how good they work for everyone else. That is another reason why I like the Tekan II's I can shoot them and then put on a flat stone and make them sharp enough to shave the hair off the arm with. Take off the practice or old blades and put in new ones and good to go. I had a hard time going from the Muzzys to the Tekans. If you use the same brand heads for a while, after time you get a bunch of them and then it is not so hard to want to practice with them.
