For what it's worth, 4 months on, I just picked one of these up and can't fault it. I also have one of the Race Elite 3s in the same style (the one with the two pockets) and this one seems to take kit a bit better, whilst still being pretty much as stable. If push came to shove I'd say the two pocket version fits slightly better, as it wraps around more, but that's outweighed by the ease of accessing kit in this one.
Having said that, it's just a bumbag, so I might be over thinking it...!
