any one shoot a 340 spine arrow out of a 60lb bow ? I was thinking stiffer spine might help BH flight
Probably quite a few people who do so. .340 is not necessarily stiff for some people with longer arrows. It just depends on length, head weight and style, shooting style... and IBO speed factors. I generally like to error on the stiffer side of the arrow chart myself. I shoot .300s at 30 inches and 68 pounds with 125 heads. I'd say go buy one or two arrows from a shop and see how it does.
