hi there,
not sure about other software, silhouette is said to have some
of the best roto tools, but i've never used it. might be worth a look.
you can easily make your tweaked custom falloff by using any
color correction tool after the roto. you can even get what you
want by using two different corrections and blending the two by
a gradient, but as said you'll have do deal with the transition
(see example below).
in the end you might be better off just doing two separate rotos
and combine them.
