I shot redlines for about a year, and the only thing that I can say good about them is that they are light and a little faster than most carbons. I believe I went through 2 1/2 dozon redlines, in one 3D season. Not because I was missing the targets, but because they did not hold their integrety. I tend to shoot almost every day from april to august, during this time period I am shooting at 50yds almost every time. I noticed that when I first bought them that they grouped fairly tight(about 4"
and they flew prety nice. After the arrow has shot about 100 shots they are shooting 8-10 inch groups and each arrow does not hit the same spot every time. When I switched to ACC's I shot the same 6 arrows for the whole 3D season, They started out shooting 3" groups and ended shooting 3" groups, they still flew nice and were still straight as an arrow.(No pun intended)Another problem I have with redlines is that when I bought them, I had to roll them to get the straight ones. One time I rolled 4 Dozen arrows and only got 1 dozen straight arrows, I find this very anoying. Comparing this to when I buy ACC's, all I have to do is pick out how many I want and pay for them. I would much rather have 1 dozen Acc's as oposed to 10 dozen redlines. I also don't believe that shooting ACC's and going 5 feet per second slower is such a big deal either. Just my 2 cents.
