I'm probably not the only one who's discovered this, but I just recently tried it - and it helps! I searched "approach flop shot", and didn't find any mention of it...
Let me first go on record as saying that I don't believe it is cheating, but it does make for a more "informed" approach shot.
Let's say you're 90 yards away from the hole... and you've played this hole before, but don't remember the slope of the green. You'd like to put the ball where it has a chance to roll towards the hole, but, with the chosen club in your hands, the target indicator doesn't open-up the "putting grid" when you click on it (either in normal, or zoom-view).
No problem - just choose "flop" temporarily and another club will automatically be chosen - then, with the flop shot chosen, the grid is visible. It may be small, just like your ability to read the green from that distance would be on a real course, but the blue/black/red features of the grid can be looked-at before deciding where you'd like to land your shot. After looking at the grid, don't forget to re-select the proper club, and shot.
When I'm out on the real course, I can see the slope of most greens I'm shooting at, why not be able to do it here?
So... do others of you think this could be perceived as using an unfair advantage, or is it just a good way to be able to have some idea of the slope of the green, while setting-up your approach shot? Is it a "glitch" in the game, or is it here to be used?
