I've finished the Outriders conversions - still some greenstuff work needed but they're ready for battle. The cloaks and the fact that they keep their miniguns close to their chest really helps to hide their bretonnian torsos. The legs don't look perfect, I'm not sure how to change that (adding some imperial symbols might make it look crowded), so I have to live with that. I've added shield decors from an old men of the empire set to the horse barding, to make it look less bretonnian.
Here's the undercoated champion:
Looking at the model, it seems only proper to take the barding option. The extra save is useful on such an expensive model, but is it worth losing light cavalry status? It is a move-or-fire unit after all... I'll be certainly using both units next time, so we'll see.
