The safety devices is very good and very cool looking but i would look at
the Patriot roof rack as well, very practical as you as have it mounted in
different stages of build from just roof bars to full rack with sides! Brown
church are very strong and cheap but also heavy and a tad  too rugged
looking for me.
Others to look at are front runner and hannabal.

I use rhino bars for my needs

end stops to carry various loads.
