Had a chance to try this and OMG was it good. No gamey taste at all and nearly melt in your mouth tender. My roast size was around 3 pounds
Brine water:
Enough water to cover roast Kosher salt ( 1/2 cup to one gal. water) steak seasoning (amount up to you, I winged it) crushed galic (same thing) any other seasonings that sound good.
I soaked a smaller one for 3 hrs. The bigger the roast, the longer the soak.
Bring smoke, I use my weber, temp to 225-250 deg. I left mine on for almost 5 hrs. Bring internal temp to around 135 deg.
There are a lot of variations to this Im going to try. Enjoy.
