This thread is precisely why when I see the issue of arrow weight, it's best for me to shut my eyes, plug my ears and sing la-la-la.[&:]
Nowhere did I sayBuckless should use an arrow that weighs less than 5grains per pound for elk hunting (his current arrow). But suggesting to someone already handicapped by a low energy setup that should also shoot arrows that weigh 10-11gpp's is truly nuts. There's no need for that. And even on an animal as big as an elk, trajectory is still important.
