In anticipation of a 800kms tour, mostly on good pavement, that will include 100kms of what might be loose gravel or dust. We currently ride on 2" Supreme and have had no problem on "reasonably packed" gravel roads. However, we have been unable to ride on a loose dust track, so we are considering other tires.

My inclination is to go for the Almotion (2"), which has great reviews, especially because of its rolling performance (fastest in its class). OTOH, the perspective of pushing our bikes when we hit loose surfaces, needless to say in an area where there are no services at all, including water, would suggest a tire better suited for off road riding -- the Mondial is possibly the better choice.

The problem is a bit complicated by the fact that it looks like the dusty segment is halfway on the gravel road, such that it makes it impractical to turn around if it happens to be impossible to ride.

If it helps, the road in question is the Cottonwood Canyon Road, between Cannonville and Page AZ.

Essentially, the question is whether the Mondial has a marked advantage over the Almotion over loose gravel and dust.
