Arrows shooting right usually does indicate a weak spine. Does anybody actually read Easton's Tuning Guide? Read the last paragraph on page 7. It says that sometimes release shooters get an opposite indication than those commonly achieved. I'm gonna bet that your arrows are acting too stiff. A quick way to find out is, if you can, just turn the weight of the bow up one full turn and see if that helps the situation. If it gets worse then turn them down from the original setting. Limb bolts are put ona bow to help with the tuning process, not just set the weight of the bow. There is nothing says you HAVE to shoot a particular weight. Where the bow tunes is where you shoot it. Simple as that. And anything over 50 lbs a deer doesn't really care.
