It is presumptuous (read: rude) to assume that nobody tried the offical method. Perhaps we just don't care for it as it is rather bland.
Also larger disks tend to have more wounds thus being harder to kill and thereby worth more.
My mistake. I was suggesting Arturo to try the designed method before migrating to a variant. I never assumed that you hadn't tried but I can see how my post could be read as responding to yours. It was not. Sorry for the confusion. Are we good now?
