Well. Back from Skegness and have to report the case was wonderful. My two SVL basses were very snug and, while the whole thing is a bit of a size, it is very mobile. Whether you think it's better than individual cases is a matter of choice. It won't go in the car, but then neither does my main rig. That's what the van's for.
All in all, very pleased with it, despite the hefty outlay.
