So what's the story/deal with the factored Stingrays that DGA has made in the past? What I've heard is that they'll take the Stingray, sand it down so that it is even more understable and even better for rolling and that it's legal.

Steve Ganz pointed out the http://www.pdga.com/documents/tech_standards/PDGA_approved_discs_and_targets.pdf

page and I noticed that there are 5 different modified Stingrays that are approved. Not only that, but there is also a modified Whippet, Aviar and a modified Viper.

Are these still being manufactured? What are they like? Is there a story that someone can share about these discs?

I could be wrong, but I think these were populaur pre-2000. The Play it Again aports in my town has the Santa Cruz factored Stingrays. Im pretty sure they are old, and were just what you described. Sanded down edges for a longer or truer flight?

#1 & #2 were the most common, #3 thru #5 were not run in big numbers and are rare.

I'm not sure if the earlier "numbered" discs were factored or that it was a mold. The newer Santa Cruz models (in last couple of years) are "factored" - meaning they have been grounded/sanded (I'm not sure exactly how it is done). As was mentioned earlier there were some DGA Factored discs Pre-2000 that were the DGA Factored Viper, Whippet and Aviar Putter. The problem I had with those were that some would be "factored" on one side of the disc moreso than the other, some a larger "factor" than others. The "factoring" on the Viper and Whippet made sense in that it made them alot easier to throw for most people. That's my knowledge of them. Maybe someone else can provide more.

You're right, I believe #4 and #5 were putters, the others were drivers.

I have a IV factored old mold Whippet made from the old stiff dx plastic. Basically they sanded the bead off. I threw it a couple of times in a field definitely less overstable. Now it's on the wall.

A more understable stingray?!?! GREAT!!!! My Stingrays hook to the left waaaay too hard :D

So who started doing it and how was it approved by the PDGA when there is a rule against modifying a disc in this way?

DGA used to do it, way back when they were still teamed with Innova to mold their discs. Then something came down and DGA switched to Discraft for their molding. Now I think they make their own.

but they still get a regularly molded disc and then modify it, right?

Terry Calhoun throws factored Stingrays.

There's some discussion here: http://www.odsa.com/forum/viewtopic.php?p=9698&sid=363e8f69ea7c51b105485751b ea5f3a9

I deleted any misinformation i might have on the topic.

Way back when, a hundred million years ago. But yes, that is apparently what they did. Although it was production modification as opposed to Joe Discgolfer grinding down his discs one at a time. Plus it was Ed Headrick doing it, not just some unknown Joe Discgolfer. And as in the NBA, the big names in disc golf get a lot more calls that the regular no-name guy. :)

I hate to bring up old topics, but if anyone was interested or curious way to much about this I found this ...

Nice... Pink discs in numerical order. I'm sure my buddies would have a field day with that one :D
