As an aside: ifantry pikes and two-handed cavalry lances both were often enough wielded with a "reverse" grip, which is about as close to the overhand as you now get with them.
Hmmm... It can be somewhat subject to debate because the front arm (I suppose this is where this reverse grip could have been most relevant, though of course, you could use a standard grip as well) was more or less intended to aim the spear-head; The arm to the rear holding the rest of the shaft held more momentum as the horse moved. It's probably a more natural approach, even on foot; You don't really aim with the arm to the rear, and you don't really stab with the arm to the front. It's more about where to concentrate the effort. This is the usual "stance" when you use the kontos.

Of course, if we speak of two-handed reverse grip, over-hand, as I think you indeed do, then of course point acknowledged
