ok, when i set in my pin,I usually start at 10yds and work back and usually have one pin for out to 25 yds. Well, I have been reading somethings on here where guys set their pin for 20 yds. This would put their arrow about an 1-1.5" high at 10-15 yds. In the tree stand. If I try this, should my arrow be dead on at 20 yds or a little high?? say an 1". My arrow seems to drop at 25 yds, I want to be dead on at 25yds. what do you guys recomend??
