How about Tri Tip.
I would cold smoke a tri tip for one to two hours. get the smoke tube going and just put the TT on right from the refrigerator.
After a couple of hours, start the grill, (you have a Genesis 1000 right? ) I wouldn't bother with a preheat, Burners Low | Off | Off
move the tri tip to the back half of the grill and cook it indirect until the meat is 120F internal.
When meat is at 120F, pull it off, and cover it fairly tight with foi. Let the meat rest while you crank up the temp on the gasser.
Turn all burners on High ( HHH) for 10 mins or so.
Sear 30 to 60 seconds a side and flip it 4 or 6 or 8 times until it feels done.
If you aren't sure, Pull it off the heat back in the serving dish and temp check with an instant read. I find 127F internal is about right for a tri tip.
