Could the transitions be more smooth, like it slides to the thing you selected instead of instantly stopping to it? Or to say it in a much easier way, slows down to what you selected instead of instant stop?
There is only a quarter of a second for the whole slide transition. a) you would likely not notice the difference, b) it would unrealistic since the sound effect will have an audible click as it locks into place. This actually works well since mouse wheels also have specific hard stops.
Once it starts sliding to an orb it is technically already selected anyway. Also, when you see the wheel spinning through a bunch of selections it's because I spun the mouse wheel very fast and through a bunch of selections. Whatever the new destination, it always takes 1/4 of second even if it has to spin through 5 stops.
In the end, it's better to be responsive to player input anyway... but trust me it will look/feel right when complete.
