Personally, I agree with you, Roskoe. I agree to the point that I don't even paper tune. I like to do it the old fashioned way. Start with a bare shaft at 6' and work my way back to 35 yards comparing POI and flight between bare shaft and fletched arrow. Every once in a while I get lucky and get consistent enough spined shafts that they have the same POI as fletched arrows and all I see going is a nock. However, that doesn't happen a lot with most carbon arrows. They just don't have consistent spine around the shaft. Guess that's why I still prefer ACC's.
