I have of this on an earlier link, they mentioned putting a ring, like key ring thru one of the ends to be able to have the hook hold the helmet. Some mentioned about using sodder(spelling?) to secure it from sticky fingers. If they are that sticky, they would probably cut the strap too.
Thinking of getting one of the N102 also. Any drawbacks?
I have an 06 and Nolan N42. I use extenders much like the ones pictured above. I had to take the gromet's off. The extension slides in to and out of the helmet lock assy. Lift the red tab and it slides right out. You may have to look around but try to get the ones that are long it makes it easier to hang and remove. Beaware some are too thick and too wide to fit through the Nolan latch.
