Is the phrase "PDGA Approved" specifically required? The Technical Standards suggest it, but it's not completely clear to me. The reason I'm asking: I've seen some discs with the phrase "Disc Golf Approved", but not PDGA specifically. I don't remember the specific model, unfortunately, but a trip to the store would refresh my memory, and I can look in the list of approved discs. Still, the question of wording, though.
thanks!
