If anyone hasn't done a brisket style tri tip, I would strongly recommend doing so. It is really fun and is definitely a very worthy sub for real brisket. The biggest caveat I can give is that it is not a cheaper alternative. Per pound, you are likely paying more for tri tip. But you can get the bark and the fall apart fibers in less than half the time. I did 2 different roasts that were pretty obviously from 2 different farms. 1 was very deep red, the other had great marbling. Both turned out great. Pics attached for reference. Again, highly recommended.
Edit: you can tell the difference in the pic of the sliced beef. The marbled one is on top. The redder one is clearer to see on the bottom right.
