We used to sight our bows in at 10, 20, and 30 yards with the old brass 3 pin sights, but with today's bow speeds 10 and 20 are usually pretty close, so I now go with either 10, 25, 35, 45, and 55, or 15-55. I go out that far for 3D mostly. My main pin for hunting is 25. I use that one and the others are just a guide that help with gapping. This eliminates the confusion of havingin to pick a pin at that critical moment. I had been using a single pin, but found that I was thinking more about adjusting for distance than aiming, which is why I switched. I hope this helps.

Like mauser said, ask a lot of questions and don't be shy. Most guys (and gals)here are more than willing to help.
