when sighting in a new bow or sight for that matter. what pin is the best to start with. i plan on shooting no further than 30 so i figured on 10, 20, & 30 yards. my sight is a tru glo xtreme series standard model with 5 pins. i figured i could do 15, & 25 yards with the 2 other pins. i know to follow the arrow but was wondering if the top pin is for shorter yardages or would the bottom be best for shorter yardage. all information will be greatly appreciated. when i shoot i hit the center dot but i have to aim about a foot high to go this.
