Dave, have you formally informed the PDGA of your perspective that:

A delineation needs to be made between a "Frisbee-like" disc and a discus like disc. Something needs to be written like: "the rim thickness can be no wider than 10% of the overall diameter."

You've had a pivotal relationship to our sport for a long time and one would hope your concerns will be given serious consideration. If you or anyone else wants to petition the PDGA for just such a rule, count me in.
