I use a nap rest, it's the 2000 because I'm basicly a hunter, not a 3d shooter. It's been awesome I love it, but if you plan on doing 3d shooting you'll most likely want the 4000 for micro tuning. Actually I've never shot 3d in my life that's why I'm satisfied with a 2000. Basicly because of it's simplicity. Good Luck. elknut1.
