I use a Game Changer, the SSG 3 bag set, and the No Name Tactical Deuce Bag.
I use the came changer on barricades, roofs, basically anything where a bipod is not the best option.
I use the small SSG bag as a rear bag most of the time, and the medium bag strapped to the bipod or over the scope anytime the game changer would inhibit movement as a front bag.
I use the SSG big bag as a rear support on roofs, under the arm, on the knee, basically anywhere a larger void needs to be filled.
I really like the straps and bungees on the SSG bags, they are very versatile bags as far as strapping them to the gun.
The Deuce Bag I use in a lot of different situations, it works really well to rest the entire rifle on like on a doghouse roof, or as a rear support off of a kneeling barricade. Sometimes I use it as a chair, both on a stage and in between stages
SSG has a website, and they are usually in stock
http://sandsockgear.com. No Name has a website but they are always out of stock, Brad's Precision generally keeps them in stock plus I like their free shipping

One bag I plan to buy is that Bison Tactical "Udder" bag. I used a prototype version of it made by Warhorse at a match in Wyoming earlier this year and loved it. I borrowed the new Bison version for a stage at a recent match that worked out really well too. I think the Bison is a little more versatile than the Game Changer, but there are still a few situations where I feel the Game Changer has a leg up. I'm not sure which one I will settle on yet, but I can tell you that I won't pack both an Udder and a Game changer.
I should note that I have tried almost everything, Armageddon, Str8, Wiebad, etc... SSG and No Name just have better features. I like SSG a little bit more, but if I couldn't get SSG the No Name combo set is a very close second.
