The importance of lie angles in irons, especially in wedges, cannot possibly be overstated. Club manufacturers present standard, VERY upright lieangles that are designed to help the "average" golfer (a slicer), definitely not the competent or even the middle handicap player. The shorter the club, generally speaking, the more important the lie angle becomes. These days, the average lie angle for a wedge seems to be around 64*. I doubt any competent or improving player will not find that lie angle will send the ball markedly left even on the best swing.
