Well I thought the 1 pin discussion was for hunting only. I totally agree on more then 1 for 3d target etc..
I just dont see much difference in knowing where to hold a single pin or deciding which pin to use in the hunting setting when the shot matters. Both take practice, both require you knowing your distance. For me I know Im fine from 15 to 40 without raising or lowering the pin much. So I just aim and shoot, don't think about the distance that much. I do try to range as many trees as possible when Im in stand but sometimes as you all know deer come in quick and I dont have time to mess with the range finder.
