you can have THE BEST GEAR and bow and arrows in the WORLD and youll STILL have tuning issues if not not properly tuned FOR you...THEN..as you are noticing you gota fine tune your bow.

goto easton's website and download their tuning guide. it is a good guide...follow the broadhead tuning section about half way down..it works..most of us here have done it. my shop didnt even offer to help me tune broadheads...exspecially NOW with seasons starting..they are probably very busy. its not hard to move a nock..good luck....
