Fugi, at the risk of being controversial I'm inclined to say that you are merely supporting 540 with more personal opinions. If you want to make a valid point please do so from an authorised source. I have no problem with the FAA/IR, as you say it is possible to self certify. Un/fortunately this isn't the case with the JAR/IR. Which is best is another issue, perhaps we can let the reader decide as opposed to trying to persuade.
