Sort of OT, but in talking with some Fazio staff members, they indicated that their bunker style is going more towards the Augusta style, mostly because their clients are usually demanding a style that is easier to maintain on the outside banks, than the traditional finger bunkers with steep capes and bays, etc.
I lamented the simple, maintenance friendly bunker styles when I got into the profession in 1977, and I lament them now, but understood why bunker design has to morph into that for 80-90% (or more) of the courses in the US.
