James, I'd suggest using "move" instead. If you can create the path line
using the points of a polygon, and then use "move", it is a lot smoother and
easier to control. For example, I made the ball, grabbed the freehand tool
and made a convoluted curvy line that would fit in a 500x500 square, hid it,
and then issued this:

on mouseUp
  move grc "ball" to the points of grc "path"
end mouseUp

and it was really smooth. It took a while (10 secs or so - my path was
really convoluted), so I decided I wanted it done in 3 seconds. So I did
this:
 
on mouseUp
  move grc "ball" to the points of grc "path" in 3 seconds
end mouseUp

Voila! 

If you can't use a path graphic, you can also use the other variations of
the "move" command to get what you want, I'm sure.
