Thanks for the info. I was able to take a doe last night off the ground with my single pin and it was true, but I had to wait until she got to the 21 yd marker. (A log I used a range finder on previously.)

I have a lot of back problems and tree stand hunting isn't going to be an option for me this year.

I've got some McPhearson sights (older) that have4 pins. I'm thinking (from your information) 20, 30, 40, and 50. But I won't change over until I know I can practice for at least a couple weeks without hunting.

Once again, thanks for the info.
