I just came across this topic and was quite entertained with the Chuck Kennedy/VeganRay exchange.
I was pleased to see Chuck Kennedy take the practical and common sense interpretation of this (or any) rule rather than the harshest technical reading possible. Good job, Chuck. I always thought there was hope for you.
I understand VeganRay's position that following rules has a moral component and agree with that principle on rules which affect the fairness of the game. On rules which do not affect the competitive balance of the game, I do not attach a moral implication.
So if you throw your disc in the bush, you can't move it out to give yourself a better shot. That is cheating since it gives you a better chance of winning. But if you were to carefully flip your disc rather than use a mini, although forbidden by the rules, it gives no competitive advantage and I don't view it as cheating-or even wrong.
When it comes to tuning discs, the only thing tuning affects is the stability of a disc. A tuned disc won't do anything a non-tuned disc will do. No magical or performance enhancing properties are imbued in a tuned disc. It is the same darn thing, just somewhat more flippy.
The down side of candy plastic is that it takes so long to break in. The up side of candy plastic is that it retains stability for so long. So it's greatest advantage is also it's disadvantage. But if any player can take that candy disc and bend it or smack it and beat me with it, I have no problem with that at all. I don't believe there is any reliable way to modify stability in a precise fashion. The best and surest way to break in a disc is with normal play. The harsher the break in process the greater the chance the disc becomes ruined or unpredictable. But if anyone thinks they can do it, more power to them.
If a player buys a new disc and throws it in a tournament it may not have his name written on it and it may still still have the little sticker price tag on it. I realize in some groups in some divisions the players will get all excited and pull out the rule books to see how much the guy can be stroked. In the old guy Pro division, no one will care. If he throws it under the basket someone might pick it up and offer a gimme. That approach to the rules is not technically accurate but it is more friendly and sportsmanlike. At the end of the tournament, whoever threw the best shots will win. Nothing immoral happened there.
