I don't know if this blog will be useful to anyone or not, but I need to get it off my chest. I have been carrying two high sixties original Star Destroyers in my bag for a long time. One is very worn and is used for long rollers side arm and backhand, and occasional high turnover shots. I still have that one and it's still going strong. What I no longer have, and haven't been able to replace satisfactory yet, is my 168g slow turning Star Destroyer. This was very useful for slow turning shots, even in windy conditions. Not only did it have a slow high speed turn, but a small return too.
About a month ago, I threw a horrible shot and deposited this disc into a lake. No big deal, I would just get another. I am still working on that, and that is the reason for the blog. This problem, is why many pros like Ken Climo carry discs in various states of wear. They don't want to lose one that they are used to and not have a ready replacement. It takes many months of wear to get a stable disc, to perform satisfactorily as a turning disc. This has been exacerbated by high tech plastics over DX. DX could be "tuned" by playing a couple of weeks on a rough course. Champion or Star takes much longer.
Beating a disc on a tree or scuffing it purposefully on asphalt doesn't seem to work the same. It is a poor substitute for natural wear. This is true for DX or high tech. Natural wear seems to produce the "magic" discs that will perform so reliably.
The moral of the blog, I guess, is to have backups ready for these special discs, so that you are not caught short like I have been. New discs are easy to replace, especially for me. Slow worn magic discs are very difficult to replace.
