OK at 8 yds 20 ft up where do you have to aim? At 15 yds? at 22 yds? At 30 yds? Wouldnt it just make sense to use the same pin all the time without having to compensate. Does to me. Yes I use 1 pin out to 30 yds now and it works. But at 30 I nees to shoot a bit high unless im shooting down the ridge of course. At 10 yds I have to shoot low unless im shooting up the ridge. Just trying to eliminate all the figuring. I am getting older ya know.
