alcaucin: That shot should be labeled 60 / 70%. Not the norm...
60/70% is more realistic. I have had mixed success hitting a full shot with reduced power. As in real golf, if you hit too deep in mulch the ball will go nowhere so make sure it is a clean hit so I do not use full backspin.
This is a shot we seldom come across and the time I wish I could use a mulligan to experiment.
