JMO and I understand those that don't want to drill into their bow but it is just a little tiny hole and the pin only needs to be an 1/8" or so. If you do a nice job it is almost undetectable. I never sell bows so I don't worry about that but if I needed to I am certain I could remove the pin and fill the hole so that it was undetectable.
I just feel the more I add glue on, tape on, rubberband on parts the more that could fail at a critical moment it the woods.
Not knocking anyone's design because there are many ways to skin a cat but seriously, how many take their arrow holder off after the season?
Regarding eflanders holder - a larger, strong rubberband goes around the riser in the arrow rest area holding a pin or stick to the back side(right side for a RH shooter) that extends beyond the riser in the back/belly. This extended pin is what your hair tie connects to that holds your arrow. Very effective but for me this adds too much to my arrow shelf and leaves to many options for failure to come into play. It also moves the holding band farther away from the arrow on a large/thick riser bow. Again, JMO. Although I take care of my equipment and have some bows that are/were costly to aquire I still feel they ultimately are tools for my goal of hunting sucess and a bow is not finished until it has the pin.
Keep em sharp -
