You bring up a great point here, and I really think it needs some testing on different types of materials.

I would think that for many types of materials, the thicker spine would not make much of a difference, because most of the wedging pressures would be forced on the starting portion of the wedge (blade), but for other materials, the total thickness of the wedge might come into play more than others. There is also a "drag" factor to consider, aside from "wedging pressure."
We would have to find blades that have the same angles, as well as measure the force needed to slice through the different objects. Apples or potatoes might make better candidates than tomatoes, because they can break apart when they are wedged too harshly. Cheese would also make an interesting test subject, because it seems to magnify the drag factor. To make the test more complete, it would be nice to measure each grind type against itself (hollow, ffg, convex).
Just thinking out loud here...
