This is why your commentary is entirely useless. You've never even seen a CF in real life. Yet you continue to talk as if you had. I would respect your opinion if you had a CF, or at least seen one in real life. But instead, you talk from pictures alone as proven by another post of yours. Go see a CF in real life, buy one. You'll find 99% of all your comments are entirely baseless. They're based on images alone, which is never going to be a good way to make accurate comparisons.
