I agree on Griz quality. Often, blood trail quality is more a result of where the arrow hits, whether it stays in or passes through, and other such variables, rather than how many blades a head has or how big it is. A high lung hit most often doesn't spurt blood, as it bleeds internally, where low lungs and/or heart bleeds profusely, as does liver. I the shaft stays in, muscle quickly contracts round it and shuts off bleeding. My goal, thus, is not to create a lot of blood on the ground, but to get a low heart/lung broadside pass-through that will put the animal down within sight, even in thick cover. Nothing beats a Grizzly for pass-through capability, esp. if you remodel the tip to a Tanto point.
