Patrick,
Perhaps you are using the word "systemic" in a confusing way. The definition from Merriam Webster:
"Definition of SYSTEMIC
: of, relating to, or common to a system: as
a : affecting the body generally
b : supplying those parts of the body that receive blood through the aorta rather than through the pulmonary artery
c : of, relating to, or being a pesticide that as used is harmless to the plant or higher animal but when absorbed into its sap or bloodstream makes the entire organism toxic to pests (as an insect or fungus) "
If you were considering the fairway bunkers a "system" then the use of systemic might have been appropriate. Perhaps it would have been more clear if you had used "universally" or "collectively' or "without exception" to describe your premise. Sorry for the English lesson.
Re the bunkers, could you expand on the description of them as being U/V shaped. Wouldn't that lead to balls going the bottom middle of the U or V and away from the walls? My course has bunkers with many capes and bays and they do indeed often impede back-swings or follow-throughs and can be deadly when the ball gets up against the edging, but they aren't U/V shaped, so it happens with some regularity.
Others,
Pat's original premise was:
The most punitive fairway bunkers I've ever encountered were at Wilshire CC in Los Angeles.
He has now allowed that (added bolding is mine):
But, as a collective, "systemically" the fairway bunkers at Wilshire are amongst the most penal I've encountered in quite some time.
Going from the absolute position to a more reasonable "amongst" position is likely the greatest concession you're going to get out of Patrick.
