I have a small paddle strop with oiled Russian leather lined with a felt support. Lots of draw there, forcing me to slow down and add significant pressure during the pass, particularly as the surface is very slightly concave. So it ends up a kind of stropping rolling X-stroke. At first, I was doing a significant number of laps, the result being that I would quickly wreck the edge. More recently, I've cut back significantly, maybe 10-20 laps at most, and this seems to be working.
