I bought a variety pack (80-220) of Diablo mesh for my ROS and I am pretty happy with the results.  I hate having to line up the holes on standard sanding disks for dust extraction and the mesh doesn't clog as easily or at least is easily cleared with a flick with a finger making it last longer.  It came with a couple foam sanding pads which help prevent overheating and ruining the hooks.  I just used the mesh to refinish a large live edge table for a friend and it performed beautifully.
