I bought a Yellow Jacket about 3 years ago, its a good product...I do not practice with field points, quit 8-9 years ago...I used to save newspapers and stuff in a box, finally went out and bought a decent target for broadheads...
I feel that it helps your confidence level to practice with what you will be shooting in the field with....I take 3 arrows and designate them as practice arrows and leave the rest in my quiver.
