Hey Dworkin, Just want to make sure you are thinking about of the right feat/s above. I could be mistaken here but I thought the following feats did the following:
Cleave:An ability to attack one or more enemies in a 90 degree arc in front of you.
Prerequisite: Power Attack
Great Cleave: An ability to attack one or more enemies in a wide 180 degree arc in front of you.
Prerequisite: Base Attack Bonus +4, Cleave
I believe the 360 Degree attack that your thinking about is:
Whirlwind Attack: An ability to attack all enemies in a 360 degree arc around you.
Prerequisite: Base Attack Bonus +4, Spring Attack, Combat Expertise
Anyways if I'm wrong, I apologize...
