I like the 3x11 Nanocloth and Roo strops on glass , lots of surface area to work with , and with razors you get nice long stropping motions without the risk of rounding off your edge. For razors I think I would go for roo over the nanocloth , that way you get the burnishing effect as well.
For compound I would go to 1u and 0.3u aluminum oxide from Ken , I hear its doing really well with the straight razor crowd. Supposedly more comfortable than CBN or Diamond given a similar particle size. And at a very palatable cost. You can get it down to 0.05 micron as well IIRC.
I think I will be grabbing all three sizes of AlOx from Ken here in the next month or so , I have the sneaking suspicion that my Christmas/birthday presents are straight razor related this year , so I finally have an excuse to start going down that rabbit hole , and to start getting some full size stones as well.
