Maybe this is just me, but I shoot every day religously. Regardless if its 6 arrows or 36. true i could sight in my bow with my broadheads but as much as i shoot i cant afford to be sharpening blades or replacing them cause i was shooting them to much. I also shoot some 3-d with my hunting bow. I cant be readjusting my sight before a shoot and then readjusting it before i go hunt again.The mechanicals give you the ability to use your bow for the different situations with out having to readjust the sights between the use of field tips and BH's. Just my opinion and I could be wrong but thats how i view it.
