bison back rib marinade

planning on doing a slow smoked bison back rib cook on the smoker, just looking for a good marinade that would suit the bison. One option would to use the stubbs beef marinade, just wondering if anyone has other sugestions. Would perfer to make my own.

4 cups water
3 cups cold strong brewed coffee
6 tablespoons Morton kosher salt
3 tablespoons dark brown sugar
3 tablespoons real maple syrup
2 tablespoons chopped fresh rosemary
2 teaspoons minced fresh thyme
2 tablespoons Worcestershire sauce

Mix all together well till the salt dissolves. Then add:

2 cups ice cubes

and stir till the ice melts.

Thanks for the quick reply kevin. I am glad your marinade does not contain alot of acid as i have read it can make the meat alittle tough. I am assuming the ice is to cool down the marinade before adding the ribs. If i cool the marinade in the fridge before adding the ribs should i just use 1 more cup of water and skip the ice?

I will be cooking this in two weeks for canadain thanksgiving, i will post the results.
I am thinking about finishing the ribs with a pomegranate glaze

Yes.

[Pom is a favorite for a glaze.]
