Heya. 5 is the toughest one...I aim a bit to the right of the pin and hit full 150 with backspin, it usually flies in pretty hard but the green does it's best to push it back toward the pin.
6 is actually pretty simple, aim a tiny bit to the right of the pin, go full 160 with backspin...it should hit the back fo the green and actually roll back down toward the pin.
