I went from pins to a single pin hha couple years back, I had the same exact concerns as you as far as trying to adjust it in the heat of the moment. But with the newer faster bows it's not as bad as ya think. I usually leave mine set on 30 and aim a tad low of high depending on yardage. Only time I will move my pin is if he's past 40 or I have time to range him and put it dead on. But I do practice that in the yard, as far as shooting 20 yards with it set on 30 and the same at 40 yards.
