Are you wanting a spot bow or a 3-d bow? Those are different animals with different setups.

Indoor you use high power lenses with clarifiers and slow very forgiving bows at low poundage.

3-d you try for more speed while still maintaing a forgiving bow with lighter faster arrows at more poundage for downrange energy.

Most are using fat arrows in both 3-d and indoor.Indoor shooters use heavy points(200-300 grain) to break down the spine of the fat stiff aluminum arrows.

3-d arrow are usually fat carbon arrows with lighter points in the 10-12% foc rang.

you can use pins or slidebars in either but the top classes in both use slide bar sights.
