Well, whether the composition ever changed or not may not have any thing to do with why some people like the pre flag. Maybe the age of it has something to do with it since all of it is over 10 years old. Who knows, maybe it plays better, maybe not. Some people will pay 50 or more times as much for a piece of Kamui, but I personally don't think you can take 50 times as many shots with it without chalking, or that a cube will last 50 times as long as another brand. Maybe some folks just like old chalk, like I do.
