That's the bag that came with my RG2770 when I got it in February. Now whenever I take a guitar somewhere, I always use that bag. It's easier to carry, lighter, and has plenty of room in the front pouch for accessories. It's very protective of the guitar and is soft inside, the only pain is that I have to wrap the ends of my DiMarzio cliplock as I don't want to chance them scratching the guitar inside the bag.
About the only thing I wouldn't do is use that bag to carry a guitar on a flight. Then I'd use one of my hardshell cases.
i've got one of the backpack gigbags for the us market and that has to be the best gigbag i have ever used. thick and sturdy with the removable backpack. i love that thing. keeps me from having to cart around m100c's all the time.
