You are speaking of these pads correct when you say double precision?
Cyclo Double Precision pads are double-sided foam buffing pads for the Cyclo polisher.. I personally just don't like this whole Edge system. Maybe it's better on the cyclo and a rotary, but on a regular DA I really didn't like it since the DA tends to vibrate a lot more. I also find that these pads tends to gunk up quickly which leads to more time having to clean them. That's just my personal opinion. You may find that you like this system with your DA.
I personally prefer the hook & loop system on my PC. So, I currently am using these
Lake Country 5.5 Inch CCS Pads 6 Pack - Your Choice!.
I find that the hook and look system gives you less vibration even with the thinner flat pads.
Hope this clears up some of the confusion. It's easy to get confused sometimes with everything that is out there.
