All I got to say on this subject is, after all the discussion, pictures, descriptions, testimonies, etc, about the FedHill and BrakeQuip flaring tools (same basic tools just carved out in a slightly different shape) I can't see way anyone would want to add any other tool to their shop.
Pop the tube in the clamp, a quick pull on the handle and you have a perfect flare every time in just a few seconds.
