re " if a tour player could hit a straight ball 99 percent of the time thats what they would hit "
I don't think that number would be that high, nor is it actual as pro golfers are constantly applying the draw and fade for the reward that a curved ball flight gives.
Like an approach on a diagonal green with sand traps left and front and back, the landing and roll toward a pin on an angle would be logical instead of risking a hazard. *
Which is just what is explained in the 2nd TO LAST paragraph here:
Because of the tight landing area, and when playing from Champ tees your iron approach doesn't have the ease of a PW high lofted shot.
In other golf sims, all of which have the draw and fade AND the option of other special skills like the guaranteed straight shot option, still , I will commonly hit the draw or fade by choice.
Not to mention the longer distance that a draw can provide (unlike the loss of distance by and off ding on WGT) since golf courses are peppered w/ hazards and doglegs a draw and fade are fundamental methods used in golf
But I get your point.
