Good stuff dude. I think my left hand is just like yours, lost 90% of the time, but after my 2nd shave I made an effort to use it. As it turned out everything was so foreign anyway that the left fumbled along just like the right. Things are about equal now with the right having a slight advantage, but I'm almost convinced that that's because my left eye is worse than my right so I have trouble seeing that side of my face. Anyhow, good luck.
