762MM,

If you hate tracking a iffy H/L shot with a trail a blind man could follow. Then look out for a botched neck shot, it is nasty. While i will say if you can do it, go for it!! The margin of error is small on the neck. You tack it in the meat around the spine on a buck and you will have your fill of tracking...with a very poor blood trail! Sorry I'll take my chance on the boiler room any day of the week over the neck.
