I personally like no 4,5 for two different reasons. I like 4 as it to me says more arabian knights more than any other so far even if it would be a little harder to have the gun designed into it. Also it to me looks light which is good due to my character not being massively strong, being more of a soldier of speed. I like 5 due to it being heavier. I have see it as a gun and i can see it being a sword to. Can see that on the back of my character. I also like it as its the one that says space opera to me as well as i can see it being a high tech weapon.
