I haven't seen one yet, but I'm sure it will look good. Adds to the whole offroad, aggressive look of the Rebel. Can't find any photos online right now though.
what I would like to see is some round bar setup that has 90 degree bends, that being something that could flow nicely with the Rebel's front especially with the way the grille is designed.That bar looks Bad A**!
I do think the round tube one goes better with the curves of the Rebel grill though.
