In an effort to stir things up some more, I would like to say that I absolutely agree with those advocating that one should learn to throw the molds that they have, and become proficient with those molds. But, as far as trying new molds, I view throwing new molds in a similar way that people view playing new courses.
I want the experience of seeing what the new mold will do, and trying to work with it. When I find consistent success using a particular mold on a particular hole, I place that mold aside and try a new one instead, because I like the challenge of working the hole with a different disc. I believe that there is a lot to be learned from doing this. And, it is fun.
If one is looking for the easiest path to success on a disc golf course, then why are they playing new courses with which they are unfamiliar? Just play the same course over and over again for the rest of your life, and dial in each hole so that you can score really well on those holes...again and again and again.
Boring.
We all want to try new things, whether it be courses, or molds, or whatever.
There are some in this thread who are stating that they have played on large numbers of disc golf courses. Anyone that boasts of playing on a large number of courses, and then criticizes others for trying many new molds is a hypocrite as far as I am concerned. Or, they just don't get it that the new mold person is in fact just like them.
