[MR] Heavy Helms and inertia

[D. Jones]

  I've always gone under the assumption that the heavier the helm, the more
force it takes to move it. I don't think the weight would make much
difference with a one handed sword, but when you start using great swords,
pole arms, etc. there is  potentially a lot more force involved.
