I would recommend that you start with a with the grain pass with the str razor (very light pressure) this is very easy to say but took me months to do it. The against the grain pass you should have a very narrow angle 15 degrees or so with light pressure. In over a year I have not tried do one pass atg without doing a with the grain pass first. I think I would get too much pull.

Try that first and let us know how it goes.
