High tech armor (one for the realism freaks)

Heh one advantage - you're pretty fast downhill.

Yeah, but you can't stop or change directions easily - as good as a sitting duck.

Either way, that looks like fun.

I think that the armors used on the Aliens movies were just perfect (well, maybe a little more protection in the arms...)
Those were small, light and strong.

BTW, I hope that 700 years in the future, we might still be able to have sex period.
