Thanks. The new S shape is close. It's difficult for me to describe, so I mocked something up in photoshop based on your design. Notice from the link that the top portion of the S is shifted to the right a bit to give the logo a more top-heavy/stable appearance.
I like the balance from this link. Can you make your design look like this? The right boundary of the top curve is alligned with the left boundary of the bottom curve. Does this make sense?
