how to have more cut by hand

[sansa]

hello there. I tried to post a question in an old thread but it's probably better to open a new one.
I read the great thread about fg400 by hand where Mike says that to remove 1500 grit the process needs about 15 minutes.

The question is: since he's using a microfiber cloth, would a wool cloth be more aggressive and cut the 1500 grit marks faster?
He says more nap gives more cut. Does wool have more nap than microfiber?

I wouldnt even attempt to cut 1500 by hand, go to a 3000 then maybe it will work well, wool and microfiber are both what i consider aggressive. Just changing to wool isnt going to save your arms.
