Hoyt Man - Yes you would have to shoot Semi in IBO. I copied the following from the IBO rules:
SEMI-PRO FEMALE (SPF)
A compound, recurve or long bow with or without a sight. If a sight is used, it can be fixed pins, moveable sight, and scope or laser type sight and may be shot with a glove, finger tab, bare fingers or with some type of release aid. Pay back will depend on the number of participants. Any person competing in this class must be an I.B.O. member prior to shooting. Any person that registers as a semi-pro during the IBO shoot year, can subsequently move to a pro class, but cannot then move back to an amateur or semi-pro class for that IBO shoot year. Must be shot from the blue stake with a maximum of 50 yards, approx.

SEMI-PRO MALE (SPM)
