One on top of the other

Both outlines on one axis, at the same scale. Sizes come from the makers’ published girths; where a usable cut-out exists, the profile itself is traced from it. Where they overlap they’re the same; the gap is the difference.

Side by side at the same scale

Drawn to scale: sizes from published girths, and the profile traced from the cut-out where we have one. Point positions along the shaft are approximate.

How the numbers compare

Differences of about ¼ inch or more are highlighted. Blanks mean the maker doesn’t publish that point.

Which one should you get?

Every line generated from the spec deltas above.

Stepping up from the Medium to the Large adds 0.3″ of girth: 7.7″ around becomes 8.0″.
That’s a modest step: comfortably inside the half-inch-per-step increment people usually recommend.
The Large is the longer of the two: 16.3″ of usable length becomes 19.5″.
