So a buddy of mine gave me a disc today that is a Z Surge but it has a little grip patch that says patent pending from the factory. Anyone else heard of this? This thing snapped out of my hand really fast today.
I can't say I've read the spec rules in any detail, but I don't think stickers, per se, are illegal. I think that since this is a part of the formal manufacturing process it is still OK. Post-factory modification is not legal, such as a sticker like this that would be applied on the user-end. Might be totally wrong on this, though I doubt the boys in D land would test out an illegal process.
These discs were unveiled a few years ago at an annual Ann Arbor Area Disc Indeuced Sports Club event, our unique One Disc Challenge. Club members sign up for the season and in addition to the usual shirt/disc/mini for joining we pass out a special disc for testing out during a one round fun time tourney. Most discs we've featured have become part of the line-up (some to DGA). My favorite is the Zone from a couple years ago. Last year we got cyclones in modern plastic.
