That is true, I guess the Simmonds front & MMC rear well set up would be ideal
I'm not so sure. I don't have any problem packing around the rear clips or getting in to reach them. I think the biggest weakness of the Simmonds setup is the external clamps on the front screen. they work extremely well, but they generate a lot of wind noise. But the windscreen channel design is a master stroke, mine never leaks even in torrential rain.
I really like the extra rigidity the factory setup gives with its pram hood frame, but on the other hand it gives a much bulkier fold than the Simmonds design. I guess there's no such thing as a perfect design.
