I use two pins. One set at 20, and the other (just below) is dead on at 35. So dead on, in fact, that I cleanly shot under a deer the other evening at 32 yards using the gap between the two pins to bracket the doe's vitals. Clean miss, no harm or foul.

Needless to say, I took the lower one off and now have a one pin sight (used to be three) that is set at 25 yards.
