Moin together, we are thinking about a bag awning, so for short trips, with two side walls. In particular the Obelink Zip. Well my question, they seem to be a little flexible in their bag, how much kink in the Kederschiene tolerate the bag awnings in general? See picture. We would like to have them from behind to forward to the bow (green line). Or does it actually only go from red to red? Thanks and greeting, Ulf
