tuning a traditional bow isn't complicated, but it does require more time and effort than most people realize, or perhaps are willing, to put in it to get it right. only three things to consider. bow, arrow, shooter. incorrect arrow spine is probably the biggest tuning problem beginners have. most likely because the guy at the pro shop who sold you arrows doesn't know a thing about traditional archery. uses a chart to provide you with proper arrows based on whatever you can tell him bout your bow and yourself. second biggest issue is a tie, in my head, between brace height and gripping the bow properly.
it's important to know exactly how far you draw your traditional bow and exactly what the weight is at YOUR draw length, which is probably shorter than you think if you are accustomed to shooting a mechanical bow with 80% letoff. Just because factory bow is marked 50# @ 28" does not mean that is what it actually is. could be 2-3 lbs more or less than how it's labeled. could be dead on, too, but it helps a lot to know all of these things before you buy arrows.
