GrizzlyStik products enhance Dr. Ashby's Top 12

In 2006 we were introduced to Dr. Ed Ashby by the custom bowyer OL Adcock. After our first meeting, we really started diving into Doc's arrow lethality research.  Like so many other bowhunters that read Doc's research for the first time - we had an "Aha Moment."

Dr. Ashby's research touched o...
