I think if any club was chosen and contact was prior to low point did we would see a divot.

That being said, and disregrding ball position and contact, is there an instance where creating a longer arc produce a steeper angle of attack

Well. If you want to get into pulley size and all of that, then I'm sure someone can exaggerate a swing and have a steeper angle of attack with a Driver than when using a wedge especially if using an outside-in swing.

But if we limit the parameters to club length and an On Plane swing, then the longer the club, the shallower the angle of attack. But divot depth is strictly related to shoulder to ground distance and ball location to low point.
