Thanks Nick, the tufts are excellent and getting used quite a bit at the moment.
Thanks all for your comments, much appreciated.
Mad Gadgeteer - As explained in the post the Victrix figures are very slightly larger in stature and I will mix in some Aventine and Black Tree to the WG figures later to make them less obvious. That said I don't find them that distracting.
Not all of WG are that constant in size anyway, with their auxiliary infantry very comparable to the Victrix. The WG legionaries on the other hand look like orcs in comparison and need updating with better ranges like Victrix now available.
