It doesn't sway side to side at all, weighs basically the same, can be used completely empty if you need to pick up shopping etc, you can open it to get stuff out without having to unpack your entire bag.
I had a saddle bag before the carradice and it was shite though it was a cheap one
I want to go carradice rear for my surly. Would you trust it with a small laptop? My basket-bag isn't big enough, don't want to fit rear rack and don't want to use 1 front pannier.
Has to be an improvement on a tapered drybag and webbing straps for long rides too
