Don't cook your tri tip like a brisket, cook it like a prime rib roast. Reverse sear works great on these, and don't cook it past med rare.
Beef ribs, most people will cook them similarly to pork ribs, only depending on how meaty they are, they can take longer than an average rack of pork ribs to get "done". If they are nothing but bones, they can get overcooked pretty easy too.
