BG - I know what you mean. I just turned 62 myself. Eyes are still pretty good - especially for distance. I use a 5 pin sight with pins set 20 - 60 yards. I was seriously thinking about moving everything down and have my first pin at 30. (There is only about 2" difference - if that) between my 20 & 30 yard pins.) Then, because I am using a heavier arrow my pins should be spaced a little farther apart going from 30 - 70 yards.
Too late this year but I may experiment with that after the season.
