With the hindsight, you always sight the same pin in the crosshairs (my 20 yard pin). After that, you raise the correct pin into position onto the deer (30, 40, etc) while keeping the 20 yard pin centered in the crosshairs. It's actually pretty simple. You can't forget to center the pin because the crosshairs are in the way. I used to use a no-peep and I'd always forget to check it in the heat of the moment.
This is my second season with the Hind Sight (Extreme version) and the only complaint I have so far is that (with a slower bow...say 240-250fps), I have a hard time getting a 40 yard pin. The ring around the cross hairs will cover the sight pin. I was BARELY able to get a 38 yard pin in there.
That being said, I will be happy to keep the Hind Sight.
