Cheers Marc.
Hello Kensar, I could not have four guys holding the lines because it would imply it was on or near the ground and the shape of the balloon would be different, the lines would also have to be vertical rather than swept back (which they would be without the posts). They are only there to give the effect of it being at altitude. I would however recommend anyone doing this to build it off a diorama as this would be easier.
