I've got the trooper. Bag size is for the amount of discs I have....really don't need something bigger. But I dislike my bag. The straps are a little small, not super easy to get the second arm in when fully wearing the pack back. I also dislike how when I pull discs out, they hit the top and bottom and are tight, sits a little higher on my back then I'd like. Ive been looking for a while, the bag I want is out of production I guess. The trvrs looks cool, but I wonder if I'll run into the same problems? Or if anyone knows where to get a rogue iron hydro bag (I also have the infinite stealth bag, but am looking for the one with more disc pockets, I have the 4 think the bigger one has 5/6) I'm not against used bags, but also not looking to spend a ton, and don't need one that can hold more then the 17 ish discs I have
