I use the tangent and it is really robust: its the curve normal that can break with sharp turn. But my node drives helper/cross section joint and i have better result with tangent than point at the next point on the curve. Perhaps try to use a nurbssurface ribbon and than once you are comfortable with that you can start massaging vector and matrix?
