Interesting Mark. My brother has always claimed his Kota longbow Isn't center shot. I've argued with him that It Is or at least damn close to It. Anyway what I'm getting at Is he pulls 52lbs at 26.5" shooting 1916 arrows (470 grains total weight) with great arrow flight. The other day while stumping he asked me If he could try shooting my 2216's (614 grains total weight) to see how good of arrow flight he got. They flew beautiful out of his longbow the whole time. That tells me his longbow Is pretty damn center shot. On center shot bows a person pulling lighter draw weights can get away with more I think when using stiffer spined arrows.
