The first things to do in tweeking is making sure you are within specs. Measure your ATA, Brace Height and check your tiller. Then I believe in paper tuning before hitting the range to finalize sighting in ( some people don't pay much attention to paper tuning though ). The paper tear will tell you in which direction to move rests and nocks, also make sure you download and read the Easton tuning guide before you paper tune. If you can get her sighted in and get good groups from field points then a good broadhead should be just about at the same impact also.
