It's not only the material being caught in the scissors it's also the material getting caught in the clips that hold the roof down which the bungee made this even worst imo. Basically to have to get the roof down then stuff all the loose material into the side to get the clips back on which are at a silly position and angle and on my Beach where really stiff and unless the roof was pulled down with a bit of force wouldn't do up.
Oh and the roof material and the secondary clips used to love getting tangled up with sliding hatch lol I have wondered whether this could happen with the SE roof too thou yet to find that out
