Before you spend the money and just for kicks try this. Sight in a single pin for 25 yards. Then shoot it at 10,15,20 and 30 yards. If you have a bow shooting around 260fps or better you'll find that with this setting you can hold just about centered on a deer's chest and hit the vitals with this single pin anywhere out to about 32 yards. Try it on a 3D deer and see the results. No yardage guessing, no pivoting sight to rattle or maybe not pivot properly, etc. And with a single pin there is no way to pick the wrong one and less STUFF in the way blocking your field of view.
