Hey Woody,
This may help you decide.

If a sight is used it will have no more than four (4) fixed or crosshair style pins. Circle pins allowed if all circles are the same size. Arrows must have screw in style points and a minimum of 4 inch vanes or feathers. Only one (1) single stabilizer being less than twelve (12) inches in length from the nearest point of attachment is allowed.

If a shooter wins twice while competing in the Hunter Class at a national or world level tournament during one IBO shoot calendar year, that shooter must advance to a higher competitive level the following IBO shoot calendar year. Once this shooter advances to the higher competitive level, he/she must remain at that level for an entire IBO shoot calendar year.
