Sorry Howard, I’m going to respectfully disagree. When NEW shooters are having left, right, up and down errors is is SELDOM equipment. TOO many folks immediately blame spine for left and right hits when 95% of the time it is “what they are doing” (FOR NEW SHOOTERS!!). Arrow spine ONLY becomes important AFTER the NEW shooter has learned to shoot and truly control their shot. Until they can do that they have NO way to determine whether the problem is them or the equipment. 95% of the time it is them and 5% of the time it MIGHT be equipment. We need to start with the most likely problem!
A shooter that has developed a decently repeatable form, can accurately shoot arrows that are 2 or 3 spine groups off, either higher or lower. Especially wood as the OP said he uses.
