Yellow Sonus is my favorite pad ever made. I can use it to cut with and then use it to polish. Had a LC orange 6.5" and literally threw it in the trash the first I used it. But, I got some 5.5 and 4' low profile orange pads and I love them.
But I have total confidence in the sonus yellow pads.
I have had one where the backing material fell off. But everytime I order from Autopia I get atleast one yellow pad. Big fan of the SFX1 polish also.
