I would also lean toward the double lung shot, my 7mm liquifies the lungs. I do practice the stated position of keeping options open. I have taken one neck shot, the buck was moving through a timbered swamp and stopped 65 yards in front of me. If the deer turned and walked away I would never see it again,when I centered the scope on the head turned toward me I could see the white patch on the neck/throat. I squeezed and the 165 lb 8 point flipped in the air landing on its back ready to be field dressed. The key is taking a shot you have confidence in making!
