EVEN if I took head/neck shots myself, I'd NEVER recomend it to others! Especially not knowing their shooting abilities!
One advantage I'll grant you with head shots vs. neck shots, is that with a hit you are more likely to leave a blood trail, and a chance of bone shattering into the brain killing the animal! STILL, I recomend NEITHER shot!
When you compare the kill zone of a lung shot to a head/neck kill zone, well, there just is no comparison! To borrow Mr. Spock's phrase, "its just illogical!!!!"
