I started a thread about this a while ago so you might want to search for it. The man that started the TAP is apperantly a fairly well respected race horse trainer and if you listen to the videos that he made he says that he only uses it on horses that are about one step from the killer pen and only experienced proffesional horsemen should try it. I'm not entirely sure what it is that he even does and I'm not quite curious enough to spend the $50 to get the full instructions but I saw nothing tooo cruel about it and I didn't here him say it was supposed to substitute any training.
