I have an overdraw on my Oneida, but I really don't like them. It takes away the forgiveness of a large brace height, and with my draw length, every mm of brace height is important.
Black Hawk (before GT bought them out) made arrows that were perfect, 32.5", good spine, and with the Speed 23 series nice and light for 3d.
Not sure what GT will do with them, but looks like there are going to keep everything the same for now.
