I've never seen a lob wedge with more than a 60 degree loft, but sydnius may be correct.
When you come to think of it, when you get to an angle of 60 degrees, and you want an object to go forward when you hit it with this instrument, you're already asking for a lot. But he is correct in that this has become an essential club for the modern golfer.
If you are not a fan of the game, you may have missed this. But Phil Mickelson was on an upslope in a grass bunker not too long ago. He was standing at perhaps a 40 degree angle to the ground with the green below him. Instead of trying to hit the ball down to the green, he turned around backwards and hit a lob wedge that sent the ball over his head, behind him, landing softly on the green for a makable putt. I don't believe this had ever been done before or since.
In relation to the Tiger Woods’ Nike commercial where he's bouncing the golf ball off his wedge and then hitting it in mid-air, which would be a solid 10.0, the Mickelson trick may have only been a 9.4. But it was still pretty damn sweet to see.
