I am not sure why you are dissing the brown disks, although there may be disks that last longer they are not that bad imo. Every time I have broken a disk it has been through my own fault and was avoidable. I normally slipped and jammed the disk, or was at an angle in the cut and wore sides until it was too thin. I am not sure where you live but here in the U.S. you can buy a package of 25 or so disks for a couple of bucks.
