I shoot fixed pins because of the conveneince when hunting. I have the pins setup on even yardage with the gap between the pins for an exact split yardage between pins. I try to keep my hunting setup as simple as possible. The more variables the greater the chance of making a mistake when making the shot. Adjustable sights are great for target and 30-D where time is of little concern. In a hunting situation things seem to happen quickly and I don't need to second guess if all my adjustments are correct before releasing an arrow.
Good Hunting.....
