I use Klingspor Gold paper for flat sanding and on the lathe I buy their 2" wide rollĀ  of the Gold paper. it last longer any anything else I've used. I used to buy Abranet 6" discs ( used with an adapter) for my orbital sander and they worked pretty good until I caught an edge and then they folded a bit and that was the end of them. Now I buy the blue 6" discs from Klingspor and they are great.
