It's all a matter of personal preference of course, but I like to have the musketeers in orderly 'march attack' poses and the fusiliers in more agressive stances. Dunno what else is in the pipeline for the Prussians, but perhaps Perry will do a pack of figures charging at trail, a pose which apparently was commonly used by the Prussians when they had to close in fast on their opponents.
Alan already did such figures for his old Foundry range, so maybe there's a chance he will do them again.
