I don't like shooting wood arrows for target, ,and carbon is stiff spined. My weight poundage is low at my old age, so I cut the arrow shelves on my bows as deep as I can get away with.Tie the thinnest low stretch string I can , and can shoot a 600 spine full length carbon with a 100 grain head out of my self bows with good arrow flight at 10 gpp give or take. I also shoot a string nock which gives me 2 reference points. Each to their own ,but that is works best for me. Replica bows I cut no shelf, and no nock on the string. Self bows, or shelf bows bows what ever suits your fancy.
