Response here from a person with nearly 40 years in the game.
An observation: I was watching the Valspar Golf Tournament on cable, and NO ONE complained about the holes there, especially not the top pros.
The regular golf world did an experiment with their holes at one point in their history. The upped the hole's diameter from 4.25" to 6.25" and do you know what they learned? Good putters made more putts.
Mach I baskets catch perfectly well. There was a SoCal player named Randy Amann whose putting style was a fore-runner of today's push-putt. When I saw him play, he was nearly automatic from 40' and he used old hard white 'DX' 86 molds. Having watched Randy play several times, I've no doubt he had the skill to putt in another way, but he developed that putt so the target would consistently catch it. This is the same thinking that led Ken Climo to develop his unique putting style. Both of these players can rightly be termed 'shot-makers' - they take responsibility for their own games, regardless of results.
What these facts mean is that it is an expression of supreme weakness to blame your equipment for your results - even if it's true, even if that expression helps shield one's fragile ego. You are an adult. You are responsible. You can adapt. Learning the correct approach to the situation, in this case, how to putt well on this tournament's baskets, is your responsibility. This game is not 'imbalanced' or 'unfair'.
I played a little match this weekend and twice members of my group said that my missed putts were 'spit-outs'. I immediately corrected them, with 'No, I missed the putt.' It didn't matter if that putt was the absolute best I could muster at that particular time. I missed it - this is case, with nearly EVERY 'called' spit-out that I have ever seen, which is probably more than most people have ever played. The point is that there is a big difference between being genuinely disappointed that you missed some shot and failing to take responsibility for your miss.
That being said, there is a lot of validity to the argument that that highest tour levels should require a certain level of consistency for targets (read: all 'identical' targets), especially if the aim is more overall involvement and attracting larger sponsors. The trade-off for enacting such a change would be the alienation of many manufacturers in the disc world, something the governing body would be hesitant at least to do...
