I know that this may have been beat to death in the past but what works best in a canvas strop, cotton or linen? I am not referring to pasting or loading a strop.

I have an old Medal of Award strop that I have been using and I want to upgrade. It has what appears to be a linen canvas heavy strop attached to the Shell strop. It has worked well for me but then again I have nothing to compare it. Does cotton work better and if so why? Does linen work better and if so why?

I read an article about stropping written by someone from Iowa State University (www.coticule.be/stropping-a-straight-razor). He had done some research using an electron microscope and found out some interesting results. According to his research the cloth (linen) removed microscopic rust and soap residue which allowed the leather to do its job better. It also was more abrasive and polished small imperfections from the edge better according to him. Does cotton do the same?

I appreciate any opinions or comment from anyone's experience.
