5- Way back center of the green. I find it easier than the front left one.
6. Way front of the green. I find that easier than the back left one.
15. Middle right. Not sure if it's easier or not. Big drop off in front of the pin.
I found playing in practice mode and setting medium pins I got to see the majority of the new ones right away. I still haven't seen the new pin on the first hole. I keep getting the same one.
