I have that same bow. I have been shooting for around 15 years, and force of habbit causes me to always start off with a 20 yard pin. I then set the rest at 10 yard increments. That 20 yard pin is a great start for me 'cause if the animal is less than that, I know that pin will work. The main thing you should consider is how accurate/effective you are at a distance that you feel that you can make a good killing shot. Just don't forget to practice and have fun, there is very little will subsitute that. It took me a while to get use to the definite "wall" that the LX has!!! Good Shooting!
