Hi Rumacara - yep, well aware of the Front Rank and "yes" they are very nice!
Sadly I started doing the Peninsular War with Foundry so it's a size thing. If starting out over again I'd use Front Rank but I am where I am, sadly. If Perry Miniatures did do Portuguese and Spanish it'd make my life a lot easier. (Offensive Miniatures do some very nice suitably sized Spanish infantry but, alas, no cavalry or artillery).
