Beating a dead horse: If you know how to play and can execute a shot, you can basically take more or less any disc (within reason for the stability you need for the shot) and after a couple of throws know how much anny or hyzer you need to execute the shot. Top tier golfers can do that.
Us? Hell, I can't take the same disc and execute the same shot a lot of the time. The reason I don't jump around from disc to disc? It's the archer, not the arrow. The discs I've chosen can be used to execute the shot. If they don't, I screwed something up. Changing discs doesn't fix my form.
How minimalism works is that you stop blaming the disc and start focusing on your form and what you did to make the disc do what it did. It's really easy to putt into a headwind and watch the disc lift over the basket and think "I need to get a more overstable putter". You don't need a more overstable putter, you need to learn to putt into a headwind. :|
Now, if you are not going to work at improving at all and are just going to throw the way you throw and take the results you get that's fine. It's a recreational activity. You don't have to practice. If you are that guy and want to try to find a disc for every situation that's cool, you can do that. The fact of the matter is that so far as advice for improving goes, somebody who wants to be a better golfer needs to learn how to throw. It's easier to focus on your form and realize it's the archer with fewer discs.
So we end up with this back and forth because we are all different and have different priorities. In the 90's when I was still in my 30's and thought I could be better I carried four molds. If I wanted a drive to finish right I put anny on a Cyclone and threw it there. When I wanted a disc to finish left I put hyzer on a Cyclone and threw it there. Easy. Now I'm old, my back and arm are shot and I'm not going to get any better. I mostly just play for fresh air and sunshine. So when I want a drive to finish right I have this beat-up DX Valkyrie and when I want a drive to finish left I have the Firebird. Easy. You can do either one, there is no right or wrong here. It just depends on who you are and what you want to get out of disc golf.
