Im waiting for Optimum to release their newly engineered Optimum Cutting and Finishing Microfiber Pads. According to Michael the Optimum Rep, its going to happen soon. He posts on DetailingBliss a lot as well as the Optimum site where he is the moderator.
Im going to try them on my Rotary just to see if they are really worth it or not.
Durability and ease of cleaning are the biggies for me. I have to get a new Power Panel since my 200amp is full, if I want to get my 220v compressor in the garage to use to clean the microfiber pads the most effective way, so its not as easy as I would like it to be..
