Bloodrunners are a good head but are not a good choice for crossbows. They can possibly open when the bow fires (they do close for flight) because of the high force applied to the arrow. If they open they could contact the bow and mess with arrow flight. I would highly recommend the Hellrazors or the Spitfires, both work well!

Reason: forgot to explain why they aren't the best for crossbows
