You could always smoke it until 120* or so then finish it off on the grill, reverse sear.I do a lot of Flank on the grill as the family loves it, wonder if it would work in the smoker as they are close to Tip being large thin pieces of beefy goodness? Never really considered it since we like a bit of char on our Flank, but after seeing this post it's got me thinking.
I bet it would be great. Thanks for the kind words guys.Than sounds interesting, I wonder how hickory smoked (w/ reverse sear) flank with my chili lime marinade would do for fajitas.
