When I had the best luck with cloning I had been making my final 45 degree cut right through the node. Then a few slices up the side(just break the skin), dip in hormone, and put in your cloning medium.
You can take the leaf set or so above the cut off the clone, like when folks lollipop their plants. If not comfortable pulling too much off, cut the leaves in half, like you were cutting someones fingers off at the second knuckle.
