lefteye, I respect your opinion, but would like to point out:
Most guides set their standards and recommendations for the "least common denominator." They rarely know what a hunter's skill will be, or how they'll react if presented with the trophy of a lifetime. They have to base their recommendations on the worst of the bunch. So, they have to recommend the 'safe' shot.
When we're out there on our own, though... We only have ourselves to make that decision. I take the best shot I know I can make. Sometimes it may be a head or neck shot. Other times, I may play it safe with a heart/lung or double-lung shot. And, I'll pass if it's questionable, altogether.
Slob hunters that can't hit what they're aiming at, are not representative of what some one else is capable of.
