Thank you so much that is super useful! I hadn't seen the expansions for Sharp Practice before.
And I love the Wurttemburgers. Coincidentally I had the very same models on my painting desk last week (though certainly not as stunning as yours).
Yeah, my friend wrote Star of Bravery and I helped playtesting it. It's specifically made for the 1809 campaign along the Danube, but it can be adapted to fit other campaigns or theatres. And it's got a very clever twist on campaign play, as well as loads of character stuff done between games which goes very well with the SP rules.
My own figures from Piano have arrived now. Just a few cavalry and infantry for research reasons.

I also got expensive but pretty cows. They're not cheap, but pretty figures and since it's just across the border availability is really good.
