There are a lot of south paws around. The right and left dominate thing is pretty much the same challenge for everyone that shaves with either hand. Some people simply cannot do it and that is fine too. Learn it if you can and if you simply cannot get it find a different path. I think stropping skills are as important as shaving skills. Getting stropping correct can make a giant difference in the smoothness and life span of your edge. I am also one of the people that strop in much larger numbers than you are. 50 on linen and 100 on leather is pretty common numbers for me. Also, how is your strop?
