Cheat Badger is a cheat utility for a few dozen different games, including a Pool Aimer for Yahoo Pool.
Perhaps because Cheat Badger's core competency is not Yahoo Pool, it is not as precise as XAimer or Pool Station.
Cheat Badger does offer a few graphical enhancements and nicer user interface than the other aimers, but its aiming is not the best. It works, but isn't great. It does not calculate pocket-banking and is rarely updated for precise changes in Yahoo. The aimer seems to compensate reasonably well to all of Yahoo's changes even without updates.
