TEPaul,
I'd agree that those items are all important factors or considerations, but, it would seem that depth, perhaps combined with location is the critical factor/s
Look at # 10 at PV
Look at # 7 at NGLA
Look at # 8 at Piping
and Look at many bunkers that liter GCGC
As to a study in depth and configuration, I think the greenside bunkers at # 18 at GCGC would provide for a fascinating study.
The deep fronting Pot bunkers,
The DEEP left side Travis bunker, and
The PIT like rear bunker
Think about the interplay of those bunkers and hole locations that utilize them or bring them strongly into play.
