FJ OEM Roof rack - Options to secure things on the rack ?

[topgear]

Hello fellow FJ-ers. 

I have the OEM roof rack and would like to seek some practical advice on how do you secure things on the rack. 

For a start, I would like to secure the spade, and a couple of duffel bags or even the folded table and chairs, if possible. 

Any ideas / recommendations?

I could not locate any valuable input from the FJCruiser forum, most of them have Baja /ARB rack or other form of flat rack.

In my view, the OEM rack is aesthetically pleasing but limited options or less practical on how to secure things on top.
