I only use two pins my first one is out to 30yds and the second is 40 yds. My Martin is shooting at 272fps at 55 lbs pull with carbon arrows and 100 gr heads. This way there is not a lot of guess work in it I like to keep my shots at under 30 so I need only one pin for hunting.<img src=icon_smile_shock.gif border=0 align=middle>
