I see you have two Cleveland wedges. I use the Clevelands too. I have a 52, 60, and 64 degree wedges.
The flop shot is my best shot. I expect to get it within 1 yd. I never chip.
I use the Nike (lv71) ball. I never put backspin on them. I think there is only one hole where I know it's difficult to stop that I might put some on.
I never flop more than 29 yds. The 64 will flop up to 20 yds and the 60 degree up to 29 yds. The 52 wedge will flop up to 47 yds but that's more unpredictable, I'd rather punch those shots.
Always hit the ball a long way left. I just miss the ding a lot to the left. If you can see the green slopes from right to left, you can make allowances for that.
It just takes practice.
