Did you go with the SB or OC for him? I gather the SB "A" plate might be a little assertive for a young shaver (though I would probably have gone for it, idiot that I was)
I did not want to scare him with too much aggression so stuck with SB. He’s a hairy bugger so at some time I can see him moving to more aggression at some time. For now well concentrate on technique.
