I have some 60-65 Acmes with RW 5.5" feathers that were a half inch too long. I shortened the dozen and put the 190 Ribtecs on 9 of them and 190 grain field points on three. This afternoon I checked them against some lighter Acmes with 145 grain points and four 4" LW feathers. I put a marker in the yard as a definite secondary and shot from a chair. At 24 yards, with my 'sunset', the heavy arrows are at the bottom half of the baseball and the light arrows tend to be on the top of the baseball, with two out of the six I was shooting changing teams, but not always the same two. I now have two 60-65 with 190 grain field points and four, out of six, four fletched 55 Acmes. What good does aiming at an arrow do for us anyway, I have never even once, shot a deer that had an arrow in it for me to aim at. You may not hit it the first time you may not hit it even the eighth time, but sooner or later if you keep shooting at an arrow, you are going destroy it. I should add that the recovery distance of the two was not seeable to me when I was shooting, they both flew straight as far as i could tell.
