DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.

When a camera's center of gravity shifts significantly forward or behind the gimbal post, the feel of panning and tilting changes noticeably, even when total rig length and weight remain similar.
Angular inertia in different axes (pan, tilt, roll) influences how a rig responds to operator input, with longer camera configurations increasing pan-axis inertia and shorter ones reducing tilt inertia.
Positioning the lens nodal point closer to directly above the gimbal post can produce more natural panning and tilting behavior.
When performing tilts with strong vertical lines in frame, aligning the nodal point above the gimbal ensures pure tilt motion rather than an arc, improving framing accuracy.
Distributing accessories like batteries and motor drivers toward the rear of compact cameras helps maintain dynamic balance and improves operating feel.
Distance to subject significantly affects the perceptibility of nodal point positioning, becoming more critical when subjects are within one to two feet of the camera.

The observation came from a single informal comparison between two different camera and lens combinations rather than controlled testing.
Whether nodal point optimization should be applied routinely or only for specific shots remains unclear and appears situation-dependent.
Some participants disagreed on whether achieving a true nodal pan is practically possible given the physical separation between gimbal and focal point in any real rig configuration.
The practical impact of nodal positioning may be subtle enough that operator skill, rig balance, and arm tuning have greater influence on shot quality.
