Looks a hybrid between the 360 and a hinge stiff, for me personally there is to much going on with the rig itself, I would keep it simple to start with, having said that there is something in the whole really short very stiff pop up section as the flick rig that Ian Russell uses a lot has a similar section.
I agree with this and i believe that when you are using a low sitting pop up the fish do not know that it is not on the bottom (this theroy is taken from experiences when diving when looking square on to some items it is very tricky to tell if they are on the bottom) and as the home in on the bait it catches them by surprise and flies straight back into the mouth
