MAN,,,There are a few GREAT heads on this short list[]I don' t get it ??...STEELFORCE ??,not penatrating ???,,you have to be pulling my leg.Your arrows must be flying sideways when they hit,,thats the only thing I can think of..
Shockwaves,,not opening ???I have shot them into my fresh Mckenzies,,with 3 rubber bands,,,TIGHT RUBBER BANDS,,so tight,,I had a very hard time pulling them open.Well,,the bands were NO MATCH for the impact.Those blades opened EVERY time and held up VERY well.If I go back to useing mech.heads,,they WILL be the ones [:-]
