Sites are one of the few things on a bow that noone can really help you with. JohnnyHildo pretty much nailed it. Everyones eyes are different. Many different styles of shooting a compound bow. It also depends on the game as well as the area you intend to hunt. I.E. will your shots be severely limited or will you have extended ranges where you will need multiple pins. Also depends upon how fast your bow is. Your higher end bows nowadays are more than capable of 300 feet per second speeds with properly weighted arrows for hunting. At those speeds you could easily get away with 2 pins for hunting out to ranges of 40 yards.
