I suppose I've got the really light version as mine are folding but that seems to be the only difference between the two. They're faster, probably a bit less comfy due to a smaller carcass and probably a lot more prone to punctures.
If I wasn't being a tart and pretending it makes sense to put super light tyres on for London, I'd be more than happy with a Brompton front/Marathon rear combo.
