C. Players may not make post-production modification of discs which alter their original flight characteristics. This rule does not forbid inevitable wear and tear from usage during play or the moderate sanding of discs to smooth molding imperfections or scrape marks. Discs excessively sanded or painted with a material of detectable thickness are illegal. See sections 802.01 D, E and F.
I have a Steady Ed (with ashes) putter that I carried and used in competition for 500 putts, without missing a single one. Of course, I only putted from inside six feet.
Once I had accomplished that, I decided that I would like to use it more often. But the problem I had was that my hands are too small to adequately hand an APX, the dome is just too high.
So, reading "may not make post-production modification of discs which alter their original flight characteristics" I figured that if I scraped off some of the dome in one spot, where my thumb could grip better, I'd be okay, since that would not alter the disc's flight characteristics, just make it easier for me to grip.
I did so, but then a friend pointed out the "excessively sanded" phrase, so I have not taken it out and used it.
I figure it should be legal, because what I have done could not possibly alter its flight characteristics during a putt. Despite what the language says about "excessive sanding," the intent of the rule is clearly to not alter the original's flight characteristics.
One of the ways you could do that it to excessively sand it, of course, but that would mainly be on the rim, like the DGA does with factored Stingrays.
Is my Steady Ed putter legal, or not?
