Mother's Day Tri-Tip

Mother's Day was tri-tip day at our house.   Who doesn't love a good tri-tip!

 Got a 2 pack from Costco.  I tried two different marinades. One marinade was a soy and worcestershire marinade, the other was a Santa Maria style (at least the web page claimed it was.)  I've never actually eaten true Santa Maria style, so I have to take their word for it.
I did a reverse sear method.  I cooked these at an indirect method.  I had platesetter in, legs up, grate on top.  I had a dome temp around 350.  This heated up the meat very quickly.  I heated the roast till internal temp of 125.   At 350 dome temp, this took about 25 minutes.

After this, I pulled them.  And they sat for about 30 minutes, while the guests arrived.  I opened up the medium egg, and it got hot.  I seared each roast about 1 minute 15 seconds on each side.   First time I've seared on my medium. I noticed that it seared very nicely, probably cause the coals are closer to the grate (compared to my large).
