Ok I have been shooting wood and aluminum for a long time. After all this talk about carbon I want to try some again. (I have tried them in the past and they have alway been too stiff, too light, and too inconsistent). I currently shoot xx78 2016 cut to 28.5 with a 125 grain point. These fly great out of my set-up. They end up at about 475 grains. My question is what arrow would you recommend to match what I am currently shooting. I want to be at least 450 grains, and the arrow has to be real consistent. (Spine and weight). I don't want to have to buy 10 doz, like I did when I first got started. Also I hear talk about aluminum loosing spine/consistency over time. I have not seen this, has anyone else, and by how much? Thanks.
