That's the thing with the flop shot - most folks think you are getting 'under' it.

No, you are hitting down - the more down the better (and easier) the flop is.

the trick is the setup

Yes, the shot can be done (and at the extreme is done) with throw away

but you'll do a lot better at it if you don't throw it away, and use the setup to leak compression (very open face, aimed way left)

in fact, you can hit these shots with a full roll horizontal hinge action - again, assuming the setup is wide open -

the setup is what allows the compression leak - the rest of the motion is the same as a full swing
