i am sighting in my new bow and i had 2 switch 2 a 3 pin sight. i was going to sight in at 10 20 and 30 yards but my bow shoots the same from 10-20 yards. so i am going 2 take out one pin and use the top pin for 10-20 and bottom for 30. which two colors have u found 2 be most effective in low light conditions between red yellow and green? (i use .29 pins if that matters) thanx for the help.
