Field tips are the points the you practice with. No blades, just a tip with a point. Don't shoot an animal with them.
Nothing wrong with Rage. Plenty of people swear by them. You just screw them on the tip in the locked position. When you get to the stand, double check that they are still in the locked position before firing them at an animal. Make sure you understand how to reset the blades before going in the field, in case one snags on something. Depending on your quiver, sometimes the broadheads will disengage when you remove the arrow, so check them again once the arrow is knocked. If the blades are open, the arrow could fly different than they do closed. The Rage should fly the same as your practice tips.
When you decide to shoot a deer, take your time and pick a spot. Don't just aim behind the shoulder. Try to find a muscle line, tuff of hair, something. Pick your spot and follow through the shot.
Enjoy and I should warn you...it gets very addicting
