Thanks guys. I think I am going with 3 pin adjustable sight. I want to go with single pin adjustable but afraid I will for to adjust in heat of moment. With 3 pin I can have set for 20,30,40 and have adjustable for father out. I am going to Colorado in September on an elk hunt is reason for me wanting to go to adjustable sight. I will probably end up with single pin adjustable one day.
