I asked Doc Griffin, my Director of Club Fitting Operations, to answer this question from Wilson Doyle, a Surgite from Brentwood, TN who wanted to know what the proper lie angle is for an iron when it is soled on the ground and how much can a given iron's lie angle be changed.
As you will hear Doc explain, there is a lot of confusion about the term "lie angle". The lie angle we can see with our eyes is the "static lie angle". However, that's a useless measurement because the only lie angle that matters is the one at the moment of impact. I like to think of this as the "dynamic lie angle" because it is what happens when the club is being swung. The flex characteristics of the shaft, the weight of the head, as well as the composition of the head (forged vs. cast) all contribute to creating the actual lie angle at impact. Obviously, this can't be determined by just watching someone swing--you need a launch monitor to do this. So if you are buying a set of clubs at retail and they hand you a club that lays flat along the ground and tell you that this is a good lie angle for you, then simply hand them the club back and walk out of the store. If they don't know that static lie angle is a useless measurement, then can you imagine what else they don't know?
