I use about depusi years. I started by buying a Mobiltruss bridge with bars 2m. as is measures the years I have bought other bars 0.50m, 1m and 2m. I now have about 40m of this structure and several angles 2 or 3 directions.
I use it mainly for the mobile disco and sometimes for the scene or the exhibition stand.
I had before that, a bridge with technylight bars. Nothing to do in terms of quality.
I find no fault in this structure is really lightweight and reliable.
The bar 2m found at prices ranging from 135 to 159 €. This is really attractive.
I would do without hesitation that choice, I do not see the point of a larger structure for use lyre or other games of light 10kg.
