I've tried them all and a stun to the head stops movement the quickest, that or chinning. Necking can cause problems with nets and I don't think it's right to have a couple of goes at the old Karate chop business .
I find that chinning as necking does, sometimes causes trauma/bruising to the shoulder area, where as the priest limits this.
Any way I will give chinning more of a go as people seem sure about the method.
Cheers, never to old to learn .
