Realize that I only had access to this unit for 2 weeks when doing a Performance Test 5 years ago. And I did not even do wings. Nice thing is we have several Members that do have this unit, so they will come in with some real world advice...me, I would...
Brine them for about 12 hours, then I would put a char on them in zone 1, just a little char. Then I would cook them in zone 4 till they were about 190° (I like them real tender). then I would put in pan, toss in a favorite sauce and then char them again on zone 1 to finish!
