RE: Flu Flu Arrows
My favorite bird/small game head is the Ace Hex-Head Blunt. It became my favorite after seeing judo's, regular steel blunts, and hard rubber blunts fail miserably--the Ace blunt worked great on the same critters (Spruce grouse--the ones we shot were unbelieveably tough birds!).
Joe Stark at Lone Wolf Traditional Archery can help you out. The Ace comes in a glue-on or screw-in.
