Just a question out of curiosity more than anything
On the face of it a large sidewheel offers advantages of greater resolution (the gap between 50-55 yards you always hear about) BUT with size comes weight and with weight comes inertia. What that practicly means that if you spin the wheel quickly to snap the focus in then the wheel builds up inertia and overshoots the point where the "snap" is optimal, in laymans terms leading to an inaccurate reading, therefore defeating the purpose of having such a large sidewheel in the first place.
