Well, the Simmons website says they're new. Got some of the Tiger Shark heads and let me tell you, they fly out of the one longbow I have shot them out of. Shot them from a 52#@27-1/2, 66" Acadian Woods Tree Stick. SBD d 97 string throwing a Gold Tip 5575 Traditional Shaft with a standard insert. They shoot like field points out of this rig.
