I shot 4 pins for years, my first shot at a deer with a bow in my life I blew, I either picked the wrong pin or missed my anchor point. I continued to shoot 4 pins until last year when I switched to one, with practice I was shooting just as good as I had with 4 pins. I have 3 pins on my new bow, but very soon I will be going back to one pin.

To each there own, there are advantages and disadvantages both with a single pin and multiple pins, with me I prefer a single pin, if you practice enough the holding high or low depending upon distance become instinct. I set my single pin at 20 yards.
