I don’t know where you play, but I am having a difficult time remembering a course with a bunch of back to front gentle greens. Regarding angles matter, even Erik concedes that they do when the ball is on the ground. That is exactly why links golf is so much fun especially for us seniors. So build more courses with less forced carries and more contour from tee through green. What features on such a course would frustrate your weekend warrior friends?
I'm in San Francisco, so suppose I take Harding Park. You can follow along
on the wiki if you want to see the green contours:
#1: gentle left-to-right
#2: mostly flat
#3: mostly gentle, mostly back-to-front
#4: mostly gentle, mostly flat
#5: complex features
#6: mostly gentle, mostly back-to-front
#7: mostly flat, with one tough section in back
#8: gentle, mostly back-to-front
#9: some complex features, but mostly back-to-front
#10: mostly flat or back-to-front
#11: some complex features, but mostly back-to-front.
#12: mostly flat or back-to-front
#13: complex features, but mostly back-to-front
#14: very complex, but mostly back-to-front
#15: complex, but mostly back-to-front, here I'd argue that a good angle helps on half the green.
#16: mostly gentle, mostly flat or back-to-front
#17: mostly gentle, mostly flat or back-to-front
#18: complex, mostly back-to-front
At the end of the day, there is only one green that even mildly slopes away from the approach shot. The greens are built with a default assistance to help shots stop.
