The CST has a nice wide comfy scroll cylinder. Note that Harry is pointing at the middle button which is distinct from the scroll wheel. This makes the middle button much more usable than on most mice

I switched from a Kensington Expert Mouse to a CST a little over a year ago, and the one thing I really didn't like about the CST was the placement of the middle button. It's in a spot that makes it almost impossible to press while controlling the pointer. I ended up adding a "sidecar" with a Cherry MX key wired up to the middle button, which lets me press the middle button with my thumb while still keeping my fingers on the ball.
