Same here, just checked, the only 6" stuff is what came with the HF, everything else is 5". I had to go check I posted the correct links, and realized they are no longer 5", but 5.5" pads, yet, the ones I got are in fact 5", so must have changed since I got them in 2018.

 

I have also had very good luck with Griot’s products. ... including their polishers.

 

Just be aware that there are three different color pads for different uses.

I have both high speed and dual action buffers, and the d/a machine will not get you in trouble with swirls, etc. that a high speed buffer can do.

I just use mine to polish my pontoon boat to a shiny enough finish. Using a high speed buffer with a wool bonnet and rouge would get me a near mirror finish, but it's too much work to maintain--and physical too.
