I have gone a different route...I remove the outer 2 cogs, thus making the prong holes actually raised from the surface of the 3rd cog...then put a ratchet handle across the hole, which fills the prong holes perfectly and lets me really crank the hell out of it. I have done this twice now and both FWs came off with far less effort than using a breaker bar on the proper tool. I think it's because if you put a lever directly across the prong holes you're not changing the direction of the torque by 90 degrees before it's applied. You can pull up on one side while simultaneously pushing down on the other, and it's amazing how quickly they give way.
