I just bought a 62" recurve from Andy McCoy (Bezaleel Bow Works). The bow is amazing, by the way. I had some cedar arrows at 23/64", 31.5" length. They weighed very close to amo and for a week or so, if I could see it I could hit it. I pull 63# at 29.5". I ordered some of the carbon express heritage arrows at 31" from 3 rivers. They recommended the 250 shaft, but the charts said 350. 350 was closer to the weight andy recommended. I went with the 250's though, and I'm struggling, and trying to figure out whether its me or the arrows. Am I just used to over shafting? These arrows are a thinner spine than I'm used to. Any suggestions would be much appreciated.
