I dont know that I truly know what a brat is, but my deer sausage is typically 60/40 with pork, and I tend to favor a salt, pepper, garlic taste. I cant find my recipe from last season to get the ratios, but I really liked it. And I've boiled them, grilled them, cooked in a skillet...all different but all good. I have to say though this last batch we used huge casings, and I discovered I much prefer a smaller casing.
