Actually this post is about things that are overrrated. The higher end plastics are overrated. Not bad but overrated.
My second DX disc that I bought got all beat up due to lack of skill. I have several different types of plastic now, including DX, and several of the DX I have had for longer than my second DX disc. All the discs I have are in good condition due to the fact that my skills have improved not due to better plastic.
Remember, I did not say that the higher end plastics were worthless, just overrrated.
If you combine this post with the post about heavily wooded courses being overrated then I would agree with both of them. However, where there are a ton of trees all over the fairway even the best disc golfer is going to hit some of them and to have your discs survive you need premium plastic.
