Many variables involved, but what I've found works out for me is that the majority of the time, after finishing up a shave, I will strop on 40 laps on linen, followed with 100 on leather. I've tried different variations, but have found that this routinely gives me the best results. After 6-7 shaves, I hone my razor on a fine coticule for a couple dozen laps with water, and strop accordingly. So far, this has been working.
