and if you can honestly say that you're batting 100% then I'll concede the point But again, there is nothing inherently wrong with speed. I personally prefer to shoot in the upper 70's of KE just for those murphy type cases. But, by the same token I saw a woman on video the other day with a 25" draw shooting Gold Tips blow through an elk. She didn't have a heavy arrow and not much speed as compared to what most guys are shooting. I personally prefer a fast bow so I can shoot a heavier arrow and still get lots of speed. It's the best of both worlds. I get great penetration and trajectory all wrapped up into to one. No speed isn't the only component but when used in the right combination it's a wonderful thing to have. I could flip the if situations around. If the animal doesn't duck your arrow, and if you don't slightly misjudge yardage, and if you hit precisely where you aim (that doesn't matter if the arrow is heavy or light) or if you have proper shot selection I am assuming you aren't advocating that it's OK to take bad shots as long as your shooting a heavier arrow)
