Sub-Roman Britain (Cavalry etc)

[Vindex]

My reason for asking is that extra weight means more balance required for horse and rider so I tend to favour slightly lighter weapons for manouerability, but with the same "thrust" and impact coming from the momentum of the horse.

Horsemen stab down at their opponants though, a heavier spear head will give you a more powerful downwards thrust, the infantry man wants a lighter spear head because he's trying to hold the thing over his head in a formation for a long period of time, the cavalry man has the advantage of being able to engage, thrust, and disengage.

Thank you. As the cavalryman stabs downwards, how do you see the balance affecting the levelling of the weapon and the balance of horse and rider?

A good horse will try to balance itself underneath the centre of mass unless told otherwise by the rider's hands and leg which then makes the balance of the weapon very tiring for the rider, if it is particularly heavy.
