Do not know what type of unfletched shaft you are launching, and what poundage your bow is. Be careful, you could have a shaft blow up near you. Also, bare-shaft tuning is not for everyone.

However, the main point of my reply is to tell you; you have to " fool" with your bow to set it up properly.

What the person at the bow shop probably did was to set the bow adjustments to factory specs and your draw length.

From that point on, you have to set everything to meet your shaft setup, your form, draw weight, etc. Which includes adjusting nocking height if it becomes necessary.
