Tom and Tom Paul,
My experience is that a diagonal should run at 20-30 degrees max. When you get sharper than that, the damn fairway looks about 90 degrees, and in fact, driving hard enough to clear the hazard, and not run through the fairway gets pretty durn tuff.
Is the diagonal really the be all, end all of tee shots? Wouldn't 14 of these carries get a teensy bit boring, just as 14 holes of flanking bunkers gets boring?
Shouldn't each of the (approximately) 14 long shots have some more variety? An open field, sloped fairway, bottle neck between hazards, flank on the downwind side of the fairway, gradually narrowing fairway to challenge/choose long versus short, etc? Would a mix of those kind of tee shots be more interesting?
And, what about average players? The problem with too many diagonals is that the good player rarely misguages the shot, while the poor player often overestimates his ability. That is the reason they aren't as popular today as features.
Just asking.....
