Did you ever think that perhaps we like to debate issues like KE and momentum? And just because we do, it doesn't mean we would not support each other. I'm a heavy (relatively speaking) arrow kind of guy. Perhaps Redline is a light arrow, trajectory kind of guy. Apparently we have, at least at some level, a difference of opinion. On the other hand, from what I read that is authored by Redline, he would be welcome in my hunting camp anytime. There might even be a rousing debate over arrow weight over the campfire. But the next day when he had an animal down, I would be a more than willingparticipanton gut and drag crew! We might even have another debate over arrow weight that over the camfire that night too!
