Yesterday at the local range I was shooting a couple different arrows. I had carbon with right helical modified T-hawk feathers 3 fletch, carbon with full T-hawk 4 fletch rt, carbon with 3 rt 5 1/2 inch bananas and cedar with 3 left helical 5 inch sheild. Out of my bow r/d long bow with a center cut riser, they all shot to within 2 or three inches of each other at 10 yards and the group expanded to about 10 to 12 inches or bit more at times at thirty yards. I was trying to see if there was enough difference in arrow flight to make going back to heavier wood for hnting a problem. What I found was that my bow and arrow combination was less a factor than my form. When I got it all right any of the arrows (carbons weighed 450 grns, cedar 540grns)would stay in the vitals at the ranges I would shoot at when hunting. I would hesitate at any shot beyond 25 yards and can't imagine shooting beyond 35 at game. I should also say that I have only been shooting trad for 2 years and that I have had the long bow less than a year so my experience is limited and I haven't done this enough to know what I can't do. Just my humble opinion.
