Assuming no wind, I always aim well left of the pin, seems that the balls always come out to the right off the club. I use my 80 yard cleveland wedge at about 85% with full backspin. If the ball lands just on the green to the left of the pin it rolls out a good bit and some to the right generally within 5 to 8 feet, sometimes with a little wind into you the shot will stop close, I've made it a few times.
Generally in a blitz challenge game I just try to be conservative and get inside of 10 feet, you will wind more than you lose that way, I would estimate that 75% of the people I play with hit that shot in the trap or off the back of the green.
