Tom Huckaby,
I think you have to look at the hole in the context of an intended drive and an unintended drive, and the results thereof.
With an intended drive I think you'd agree that you're presented with a fairly benign approach shot.
Hence par, or birdie is likely.
An unintended drive leaves one with a more difficult approach shot, but, in the context of the good or great player, I don't see the overwhelming difficulty in the shot.
And, I view the results of an unintended drive in the context of a par, not a birdie.
If a good to great player hits it left, a lofted iron approach should provide a reasonable chance to make par, perhaps an occassional birdie or bogie as well.
I just don't see the high numbers you reference, from good to great players, whereas, I can see those numbers at holes like # 3, # 4, # 11, # 13 and others.
I don't think a hole has to be diabolically difficult in order to present an interesting challenge, and # 6 would seem to fit that mold by my standards.
