I would say since most lie angles are ridiculously upright as it is and most iron lengths are longer than old standard (which makes them more upright as well) that the lies tend to get flatter.

I went from standard to 2* flat. Also, how stiff the shaft has an effect on it as well.

Good call Jim. The club industry has changed in the last fifteen years to more upright lie angles as their standard lie angle.
