I always finish with very very very little or no pressure on all stones. When setting a bevel you can use pressure, but finish with no pressure when the bevel is almost set. As for treetopping hairs off the 1k it really depends on your hair. I have really fine hair and its hard to do it with my hair. My leg hair though is quite easy. You could try your leg hair, but my main test for bevel set are TPT. I also like to be able to shave my arm hair quite effortlessly off the 1k.
