Well, I think the best advice on blobs (at least the one that helped me
the most)
is that one must remeber that blobs are *fields of strength*, not
spheres or
cylinders. 
In order for two components to join, they must first of all intersect,
and the 
threshold value must be greater than the sum of their strengths in the
intersecting
area.
Another trick that helps a lot when designing blobs is using transparent
spheres
to visualize the edges of the components, so for each spherical
component you could
have something like:

/*
blob
 {threshold 1
  ...
  sphere {<1, 2, 3>, .5, 1}
  ...
 }
*/

sphere
 {<1, 2, 3>, .5
  pigment {rgbf <1, .8, .8, .8>}
 }


Hope it helps.
