From this page's description: "[...] you will be surprised by the considerable agility of these zweihanders and the amount of control you can have." I don't agree with this - it feels just as cumbersome as it looks. At least on mine (flamberge blade, with the "edge" bevel option), there is no distal taper - the blade doesn't get narrower in both axes toward the tip - so compared to something like my Red Dragon synthetic longsword (which is substantially smaller and more flexible, I know) the weight of the blade far from the hands feels much more significant. I have no idea how a real greatsword's weight distribution feels so I can't say whether it's accurate, but all the metal in the hilt of this one certainly helps shift the point of balance.
I am 6'4" - picture for evidence :) - but by no means in good enough shape to use a greatsword - or any sword - competitively, so I can imagine a stronger person not having too much trouble. I enjoy aimlessly swinging it around in my backyard regardless, and it looks nice enough to go with my Halloween costume, which were my main intended "uses" anyway.
Since it was interminably out-of-stock from SoCal, I had to go to their source, Blackfencer, in Spain, and as I am in Texas the shipping was like 150% or more of the price of the sword itself. So obviously get it from SoCal if they're closer and it comes back in stock. I like the red cord wrap.
