A cubic_spline need to start and end with control points. Those points 
are not part of the visible spline. The part that you see start with the 
second point and end with the second to last point.
If you want a sharp bend, then, you need 3 points for that bend : The 
first in line with the segment going into the bend, then one at about 
the center of the bend, then one in line with the segment going away 
from the bend.

In your case, that mean a sphere_sweep with 7 or 8 points as follow :
1) start control point
2) effective start of the spline (you have it)
3) start of the sharp bend
4) middle of the sharp bend (you have it)
5) end of the sharp bend
6?) (optional) middle point of the long segment (you have it)
6 or 7) effective end of the spline (you have it)
7 or 8) end control point
