What shape are the dg alloy nerf bars if you get them for the 300ex? Are they a square full of netting, a square with a rounded part at the end with no netting in the rounded part, or square with a smaller square on the behind them on the outer side of the quad with no netting? I plan to order from rocky mountain.

 

they're just square without the extension on the back like on 400ex's. heres a pic

 

Thanks for the reply.
