I am looking to buy a slider sight for next deer season. I want a slider sight as my next one, but am not sure how many pins to get. I mainly hunt whitetail, but will eventually hunt out west with my bow. I have always used horizontal pins, but want to switch to a vertical pin setup. I am thinking 2 pins(maybe 3), but I have read where a lot of people shoot single pin and love it. I am going to want to buy a used slider in case I don't like it I won't be out too much money. The main reason for the slider is to shoot further distances for western hunting and just for practice.
