Thanks everyone for the replies, esp you Tim.
Ironsidegnr's reply is useful too. I too, started with this stroke, though I did TRY and do a 'proper' X stroke like the obedient little fellow I am.
I find it a much more natural stroke. IF (if) I had an area of the strop that was, well, 'f'd up' so to speak, I guess it may be an issue, but my strop is good. I may be arrested anytime soon, but I'd even go so far as to teach OTHERS to use this method, rather than the X stroke. I think the X stroke causes some over thinking and leads beginners to nick (possibly). However, as previously stated, I don;'t know what I think, and also, as previously stated by another, I'm mad.
