Now that the Vostroyans are OOP, the mainstay of GW's Imperial Guard are the Cadian models. 

All very good and hard sci-fi but lacking in the weirdness and richness of the 40K universe covered in the novels and so on.

That's one of the reasons I like the Ventrillian conversions. Feathered helmets and swords for future grunt Infantry.

With a few of the new plastics left over and armed with two boxes of Pistoliers from the Warhammer World store, I will start a new Ventri.lian force.  My first iteration will likely go to the second hand market.

These models have the backpacks and scabbard swords from the Les Grognards models from Wargames Atlantic.

 More on Wargames Atlantic later.
