I asked this on the PDGA MB, but haven't got much of a response. The new tech std doc calls for discs to be marked to indicate what mold they are, and it lists hotstamps, indelible markers and mold engraving as examples.
I haven't bought discs in awhile, but if a new disc comes out with a custom hotstamp, and you can't tell by any indelible marking or disc engraving, does writiing a code/abbreviation on the bottom of the disc with a ball point pen suffice?
I don't think it does. What do you all think?
Also, do the changes to the Tech Stds that went into effect 1/1/08 apply to any disc made on or after 1/1/08, or just discs made with molds that were approved on or after that date?
