When he first posted he said "I've heard their good" then later on he posts that he is canvassing kings. If he doesn't give you the true facts from the start it makes you wonder. The funny thing is that here and on another forum he has said that he has been going 20 years and yet no has come forward to tell us about when they used them. I would of thought that in 20 years someone on here would of come into contact with them.
