Where is your proof Neal - your experience with one friend's snake or perusing through videos? I'm confused as to why you would pick a forum fight based on so little direct experience with an animal.
I don't keep cobras, but I've handled them. After you and Crotalids did your little round of slap fighting on each other I asked a very good friend of mine who keeps rinkhals, coral cobras and true cobras (and has done so for years) and he laughed and claimed that they can strike from any angle, hooded or not, awkward or not. In fact he took a dry bite on his forearm from a taiwanese cobra that he estimates had to - while hooded - strike up almost 2' to hit him.
....and that anyone who perceives that their strikes are limited will be in for a nasty surprise. So, forget Crotalids, I wan't to get back to my friend Chuck and tell him he's wrong. Before I use you as an example, provide me with the ammo to do so.
