The Knight Titan isn't a Knight; he's waaaaaay too small for that. He's a Riptide, for when I ally with my Urban Warfare Tau, converted from a Geara Zulu toy a friend bought me while he was on holiday in Japan.
More details, including the extent of my conversion to the kit are here: [url]http://www.lounge.belloflostsouls.net/showthread.php?38689-Imperial-Guard-121st-Bifrosti-Riptide[/url]
I've always hated the concept of Rough Riders. I once toyed with the idea of some on mechanical horses, but I couldn't find a manufacturer, and their rules have never been anything but terrible, so I've no inclination to make any.I think Rough Riders are only classic (RT-era) unit you are missing, while the Valks are the obvious new school omission - will you be adding either?
As for Valkyries? I just hate the model. To be honest, I don't really like any flyers. I do have one. It's been assembled on my desk for about four months and I've just not had the inclination to paint it. I'm sure I'll get round to it in the end, but flyers are just a 'duty buy' for me really. I know some people just love aeroplanes, but I'm not one of them.
Which bits? If it's the mech, follow the link above. If it's infantryman bits, be specific and I'll let you know.I recognise some of the parts, but where are all the parts of the conversion from? It looks really good and fits in really well with the IG. The head especially makes me think of the Death Korps of Krieg ...
