Who is the guy shooting in the last pic? He looks like my old PSG.
I am more of a fan of the dual rate gun if it's not hard mounted to keep down on the jams. The rounds have quite a tendency to snag in the shoot as you traverse, which stretches the links and causes some horrible jams. With the lower rate you can get on target and then cycle up as needed. Just a couple things I learned about when I watched the dillon video.
And for gods sakes get a "laser"!
