How many times have you switched your bow tech? Looking back on the past 4 bows I have purchased it seems that I have had a different draw length or arrow length & weight according to the tech behind the counter. I know that each bow is some what different but don't you think your body measurements are always the same? Before gaining more experience my first few bow set ups were all wrong. How can that be? Arent all the bow techs trained and certified? New archers will have no idea and will listen to the guy behind the counter and trust what he or she is telling them. Also have had problems with techs not cutting arrows all the same length. My suggestion is talk to fellow archers and see who they use and why. I finally found a tech that I trust 100% and is the only one who will touch my bow.
