I was unaware that Bonanzas came with vernier throttles. Perhaps that aircraft type is a little more tolerant of that arrangement, but I still dislike the idea. The only aircraft I flew with a vernier throttle (later, unapproved installation) was a 185 floatplane. With no brakes, having to fumble to close the throttle is not good.
You need to take the throttle in your hand so that the pushbutton part fits in the palm.
Some vernier controls require the pushbotton to be nearly flush with the knob to release. That's less than easy with your palm. For most aircraft, the engine controls are much lower on the panel, and the geometry of one's wrist does not accommodate palming the button easily.
For prop and mixture controls in singles, I really like vernier controls. For throttles, I prefer "direct" control. It works on every PA28, and all twins just fine!
