i was expecting _no_ falloff within the cage, the hand moving as a unit, and the falloff occuring between the cage and the forearm in digmans example picture, so you could , you know, _pose_ the hand, without mangling it.
shouldn't a pose tool have hard start and stop points? the stop point being the pivot point. i guess the gradient is there to try to preserve then mesh upstream of the pivot but seems to be more trouble than it is worth.
