Abrasives for a 9" sander

[Willie71]

I bought one of Nathan's 9" sanding discs. What do you guys recommend for paper for it? Do you buy round paper, or cut regular sheets to fit?

I do both for my round machine depending on the paper I need to use.

I believe most guys who use disk sanders a lot buy their favorite sheets, trim them, and use the cut-offs for hand-sanding. It's a very versatile and efficient way to work.
