SYW Prussians and Austrians. Well-matched and versatile armies.

I would say WWII circa 1943 east front with my own rules, this combination is my current pleasure, but I have just cracked open my Pendraken French 1809 army to paint (the Austrians are on stand-by), so  who knows what I would choose in say a months time.

I think it goes without saying that all wargamers' wish-lists are subject to change without notice. 

Many a true word - says he having laid his later C19th French out again.
