This looks just great.
Its literaly what I was looking for, sometime ago I had a really bg problem with other scatterer program making this kind of chains and other stuff spline related. It was always puting holls in it.
Spline Scattering should have one more option "Distribute on whole spline" at this moment you can make really great things but..
If you reduce the count and it does not "reach" the end of spline you can have really uneven distribtion (Jitter pumped up).
