I have a Saracen and, now, a Fortune Cookie. I really like the Saracen - it fills space in a variety of obstacles very well, especially off of tank traps and the like. It's easily manipulated to conform to the obstacle, too. Plus, Chas is a cool guy who worked with me to get a bag in a non-standard pattern, and kept me updated on the progress with the bag during it's manufacture. Can't say enough good things about his customer service.
That said, I was finding it difficult to shoot some typical "heavy bag" situations with it (for instance, free recoil, and off of narrow fence rails). I attended a clinic w/ Jim See a couple of weeks ago, and asked him about my issue with steadying the gun in a free recoil situation. He immediately swapped the Saracen with one of his OG Game Changers. Just like that, free recoil became easy (using the technique Jim describes in various videos). Something about the difference in fill and/or shape between the two makes a big difference in how they handle that situation for me (it's the difference between wobbling 3 MOA, and wobbling 1/2 MOA). I spent the rest of the day swapping between those two and the mini and full size Fortune Cookies. I ended up settling on a full size Fortune Cookie, because it was the equal of the Game Changer in every situation I tried, but it was superior on things like pipe fence because of the grippy material on the inside.
If I drive to a match, I'll almost certainly have both bags with me. Flying to one, it may just be the Fortune Cookie. And, I could see buying a Game Changer in the future, too, and spending more time with it. There are subtle differences in the handling of each that I'm nowhere near nuanced enough in my usage to realize, yet.
Also, I tried the non-OG GC, and the waxed canvas GC. Purportedly, the waxed canvas bag should grip a pipe fence better, and it does seem to... a little bit, but not like the big difference the Fortune Cookie had in that scenario. I could use either, and didn't arrive at a definitive decision between the two, but was left kind of feeling like the Cordura OG GC treated me just a tiny bit better.
Edit to add - I missed mentioning that the non-OG GC was the only one I wasn't very into. Compared to the OG, the waxed canvas GC, the Fortune Cookies, and the Saracen, I feel like the lighter weight GC is the definite odd man out...
