I absolutely love these! I started out with 5.5" Lake Country ccs pads, but I will never return!
*This is all via rotary*
Discontinued Sonus Pads
Pros:
-Beveled edge eases transitions on body panels
-Pads dont "soak up" polish very easily
-No hop, skip, or vibration at all
-Very Cost-Effective ($9/pad)
-Thick (especially w/ 3M Backing Plate)
Cons:
-6" is a tad large is some areas
-You have to go through CG to get them
-A little bit difficult to clean compared to CCS pads (probably due to thickness)

Just thought I'd share my thoughts
