Mixed feelings about helicopter.
Yes it sort of works.
But it just looks so crap !
If you're trying to impress someone (read: showing off) ripping out a fig8 or sidearm just looks way better, goes further and gives the slinger a wee bit more kudos
Hell for showing off underarm is also pretty good. Helicopetr - just never took to it.
As for battle shows - we've had the warrior versus other warrior thing on recently. watched the first one. Never bothered watching the rest.
Samurai versus viking - come on ! samurai 99 times out of 100. No question. Better armour, better swords, much better training and fighting technique. Big arse bows - samurai bow is about the only thing that can give the old english longbow a run for it's money.
