head design i think is really important. i shoot steelheads short like field tips and low profile. if you shoot something longer you might want those longer field tips they sell. but everyone is quick to jump on the mechanical wagon but there designs are bad. there are so many that are fat, or have so much blade sticking out might as well shoot fixed heads. the spitfires shoot true to field tips my dad loves them. i just like the pathfinder tip on the rockets penetration is excellent.
