If it were ever to happen, a switch to smaller baskets would probably fall onto Clubs that want to run higher tiered events to come up with the cash.
So this is going to fall on the shoulders of the folks who work their a$$e$ off to make the tourneys run? Probably the same ones who busted their tail to get sponsorships just to get the course installed in the first place? Now you're going to tell them, "Soo yeah, why don't just go ahead and buy some new baskets...like all of them. It's only $5400 per 18. Shouldn't be hard."
Some of you are just blowing this off as if it isn't a big deal if it is implemented. I think this issue is a very big deal since this sport is sooo volunteer dependant. Piss off your volunteer base and they will likely walk away and never come back. I've seen it too many times in other contexts. Heck, I was a volunteer for something (not disc golf related) and got stomped on a few times and left. Haven't been back to that situation since.
And I still haven't seen a viable plan for making these large sums of money for smaller baskets appear.
