I shoot a 5519. I had mixed feelings about this, because I wanted it for a hunting bow first, and a play around/target bow second. But the pin is just so dad gum bright that seeing it even in damn near total darkness isn't a problem at all.... so I went with the 5519 and I'm glad I did.

If you have any vision trouble ... any at all... go with a bigger pin. Smaller pins might allow you to be more accurate at longer ranges.... but a pin you can't see when you need it isn't very accurate at all.
