RE: Arrows can be confusing
hotload, I agree with X-Ring. I've been shooting the Redlines for about 6 months now. They are a very good arrow. The weights and spine always match closely. I shoot the 460s at 320 or 340 gr for 3D and 410s at 375 gr for hunting. That is out of 60# bows. I've also had good luck with SME Epsilons and PSE Extremes. The SME arrows are a little heavier, the PSEs lighter. All good arrows.
