I've used SSR2.5 with the following pads -
- Lake Country 6.5" variable contact cutting (yellow)
- Lake Country 7.5" curved edge (white)
- Edge Original DA light cut (green)
- Edge Durafoam DA light cut (green)
The product worked well with each pad. When using a more aggressive pad texture, you will probably need to follow-up with a finishing polish on a polishing pad. When using a less aggressive pad, it may be possible to skip the finishing polish step.
