BuckSkin-

TAP provides by far a more technically accurate way to match arrows to a bow over ANY spine chart.

I will even go as far as saying it will take you to the next level of archery through proper shaft selection. I get emails everyday thanking me for this tool because of how easy it was to select the right arrow and get tuned so quickly.

Charts will get you most likley into the right shaft......TAP tells you how long to cut them to the 1/10th inch and what point weight to use to the grain!
