Tuning is more important than just about everything because it affects accuracy as well as how much energy it has when coming into contact with an animal. I reccomend taking your bow to the best bow shop in your area and asking them to check timing. I have noticed that these bows often comeun tuned even though the factorydoes it on brand new bows( Even solo cams and cam 1/2s). once that is done paper tune your bow and the finally check broadhead flight which should not be affected much.
