Now hush boys! Be nice to each other, or I'll have to start moderating.
@ Calsash & LordDain:
Don't get too defensive without thinking about it. They have a point that the Hobbit Design is more fantastic than the LotR Design. I think it's great that more people are trying to give their input here.
Were is this
quote about the dwarven strength coming from anyway?
@ Hüter:
Well you kinda shot yourself an
own goal with your first post.

As you can read
here from the chronicles Weta
did built the boarbows as functional props. If someone knows how to do that, it's them.
But yeaaah, as you said, you're more interested in the usability. I'd say a crossbow is a pretty complicated weapon in every form. Cranking up the string is always hard. And a normal Crossbow-bow is also made of metal, so i guess it would have similar weight.
Honestly as I said I think the only downside to the boarbows is simply that they don't
look like crossbows. But then again, that's kinda a very
unique thing to achieve.

I think you're right that the Hobbit Props are far more stylized than some of the LotR Props. But I don't think that's a bad thing. After all the Hobbit
always was the more playful book. "Realistic" is the wrong word to judge the designs by, because there simply are no
real dwarves. So why should the dwarven gear be limited by what a realistic human can use? The better word to use is "practical" in my Opinion. And in that Weta is king.
In comparison to every other fantasy dwarf I always prefer the Weta ones. Their Armor, their used materials and workmanship makes sense in itself. Every Prop is made with the needed details to fulfill its purpose. All you have to do is assume that there is a dwarf that might fit into that.
Iron Man is a good example for that. They had a real metal suit made for the first movie. RDJ hated it, because he couldn't really move in it. So they made it fully with CGI, RDJ could perform to
make us believe the suit could exist, and the movie was great.
I think that
extra fantasy tick was only that much apparent in the Hobbit, because as Val said Elves and Humans are (visually) much more alike than Dwarves. There just were too few Dwarves in the LotR. Gimlis too much in traveller garb.
And it's not like there weren't any "unrealistic" elements in the LotR. Anyone remembers the Witchkings morning star, with the size of a small car?
