[Translation of the original French comment]
I'm flying with Topfex since 13 years and I am always delighted.
The topfex is just a good hang glider, a little strongly to control.
The minimum sink rate is equivalent to that of my friends on atos or stratos, i go up more easily than them but i am much worse of speed and glide ratio.
And then, as it is relatively large, i can take my children with me.
I love this hang glider.
