Shine Ola since I found this to be a better product than Optrix.
I used to use Mapleshade Micro-Smooth followed by Optrix and then the Mapleshade Ionoclast gun. There is a cumulative effect as advertiesed by Mapleshade. I still use the Ionoclast since I found it brings out additional detail and, more importantly, provides a more "natural" or slightly less mechanical sound.
I no longer use the Micro-Smooth and Optrix combination since Shine Ola by itself was a better improvement by a slight margin. And I didn't have to spend time buffing my CD's with Micro-Smooth.
