dave,Biggest mistake I see at the range with a lob wedge is NOT having it far enough back in the stance when hitting a full shot.Middle of stance is no good,neither is just to the right of middle,the ball needs to be RIGHT back
If you are going to put the lob wedge so far back in your stance, why not use a club with less loft in a more "normal" position in your stance? Moving any club that far back in your stance reduces the effective loft quite a bit.
