I question just how much Golden Age players bought into the strategy as written by the GA gca's. Other than Hogan saying he might aim for the rough, I can't recall too many players of that caliber really talking about playing the angles. However, if one of the "expert researchers" here can find some substantive quotes to the effect, I wouldn't mind seeing them.
Maybe they all did it and assumed everyone else did as well, so it wasn't worth addressing.
Me, I tend to do what I think works best for me. That changes on a daily basis.
