Cloud Trapeze vs. Faery Trod

[Mysterio]

Ok, I need some expert info for this one, since I've never used these two spells. Do they both teleport a mage and the squads assigned to him to a province? In the manual, the text for Cloud Trapeze makes me think it teleports only the mage, while the text for Faery Trod explicitly mentions the "caster and his army." I need to know if I need to research Ench 5 for Faery Trod, or if Cloud Trapeze will suffice at Ench 4.

Also, besides needing forest provinces for Faery Trod and getting lost, is there any reason to use one over the other if they both teleport mage + mage's squads?

Thanks!
