I carry a 54/10 and a 58/8. I seldom use the 58. Does anyone know if playing a wedge, face wide open, significantly increases the loft? If so, is there a rule of thumb? Is 5 minutes of face angle worth 2 degrees loft, for example? I looked all over and most sites speak about changes to the effective bounce. They are vague, however, regarding specific changes in effective loft. I think it would be instructive to know what to expect…all else being equal as possible.
