A few things I think are important to add in this conversation and to comment on multiple posts I've read.
1. First off, the argument that "everyone has to use them so it's fair" is, IMHO, misguided. Fairness is not and should not be defined as unfair for everyone. I don't want to live in a world where I'm sent to prison for a year for speeding and told "well, that's what the last guy got."
2. I don't see a time where the PDGA mandates baskets for events anytime soon for a few reasons. Mainly, the PDGA doesn't produce a basket. This means that they are using outside resources and essentially endorsing them. I see a lot of pararells where this occurs - "Spaulding is the official ball of the NBA" - but I don't think the PDGA is ready to take such a stance for or against a company. Imagine if they said "it must be discatcher 28s. That's a slap in the face to Discraft, Prodigy, DGA, DD and all the other companies that make quality baskets.
Let's say, for the sake of discussion, that happens. So now Emporia is told "if you want to continue to host the Glass Blown Open, Jeremy, you have to get rid of your own product and use your competitors." That is NOT a good look for the PDGA.
3. Mandating that you can or can't use certain baskets in events greatly limits a lot of courses / clubs from running events. The PDGA still is in a quantity state as a organization and isn't quite ready for the shift to quality.
4. Different baskets react differently to different putts. For example, I putt nose down and typically pretty flat. Mach 3s and 5s, that most people have issues with, I don't. I have more putts bounce back on something like a Mach X or a Prodigy basket than I do cut throughs on Mach 3s. I truly believe that someone who commits their livelihood to playing the sport should do offseason practice on multiple types of baskets and see how certain baskets react to certain putts. Is it worth going to a pitch putt instead of a spin on a Mach 3 based event even if you aren't as comfortable? This is somewhat similiar a lot conversations of anchoring putters in golf.
5. This isn't the PDGA's fault, rather the companies that produced the baskets.
