If you only have one pad, then that's what you'll have to use though honestly IMO you'll need a polishing pad or finishing pad to derive the best results. I can't find the orange Edge pad, so I'm guessing it is intended for light cutting. So I'll suppose that pad combined w/ SSR 2.5 with go some ways in eliminating (or reducing) the amount of swirls. Flip it over and try it with the SSR 1, but again that is likely not the optimum combination for finishing. After that I would go straight to Natty's forgoing the SSR1 by hand step. For the future I would invest in some polishing and or finishing pads.
Edit: I see JP weighed in ahead of me. We seem to agree, so it must be right.
