Could I jump from 60 to 120 grit on the drum sander or is that too big of a gap? I have a bit of 120 laying around and wanted to pick up some 60 to flatten a bad cutting board glue up on my part but am not sure if that is too big of a gap between grits.

Secondarily, what brand paper are peoples favorite these days? I'm in a bind today so have to likely get supermax as that's all they'll have in person but am curious what others are using.
