I've never tried that paper, so no opinion. The stuff I really like is Norton 3X gold-colored 320. I like the backer paper, and the grit works well for me. An alternative would be the 3M 261U, but I like the Norton better in 320. I also have some Norton 400, but that didn't seem to add any benefit v 320, and the 320 cuts a bit faster.
I use the 3M in P600 for other situations.....especially smoothing between coats of shellac. It's really good stuff, IMO.
