Bags or bipods?

Here's footage of the GAP Grind. It's basically where 3-gun meets long-range shooting, with small plate targets, lots of position shooting, towers, berms, barricades, tunnels, window apertures, cars, boulder piles, and so forth. Everything is on the clock, and 1st-round hits get max points. Looks like one of the most challenging and fun competitions out there.

You can see a guy sponsored by GAP shooting with the bags on his stock forearm and elbow at 11:24. He's extremely fast, BTW.
