The only bunkers, I flop out of is on Beth. All the other courses, using the Flop Shot in the Bunker is not good.
Flop shots are also good in 40/50 rough close to pin... 8-25 yrds,
The Flop is also good from the fringe, but has to be hit with less power than you think or you go way past the hole.
Most of my Flop Shots are with Full B/spin, except for fringe... maybe less spin (still scared of the ball going 2inches with full b/spin on fringe...lol)
Everybody is different at how they play or which types of shots they use. Also depends on what wedges you might use.
The Flop is my Favorite and the shot I would use when close to green... within reason and I don't think it has changed or playing different.
