I got some Bestem Arial knobs. I am going to try your suggestion too for more length. It really helps give fine movement input to the bird.I lengthened the sticks - easy to do. Unscrew the top half completely, then unscrew the lower section until there are about three or so threads left, then screw the top section back on again. The sticks will be longer and slow pans are made a wee bit easier.
