We got a couple recently. They are trimmer than the old ones. By that I mean, they seem to be less bulky between the legs and the tabs are smaller, as you pointed out. I'm not sure they're taller, though - at least not on Sebastian. I had some leaking with the old ones to start with, but I think that was more Sebastian's size than the nappy. We've been using the old one now as well, and it's fine. I think it's an improvement with the fit, definitely. But I think for S, the BG pocket still fit better and seem better for containment.
