I think when John Gregg said that the Gregg shorthand system follows the natural slope, he was refering to the cursive handwriting used at the time. I've ordered a couple of books on Spencerian script on Amazon (my first experiment with ordering abroad and having things shiped to Russia), to get my handwriting in line with my shorthand. I think a beautiful cursive handwriting script and Gregg would compliment each other well.
Does anyone else have problems with their Gregg outlines not being slope enough because of their handwriting habbits?
