Kojak tyres opinions

[Loomis]

Hi, What are peoples opinions of Schwalbe Kojak folding tyres? I bought a couple a while back in 20/26, with a view to replacing the Marathon Racers I have fitted at present, to my Giro 20. From reading rolling resistance figures and some opinions, they do not seem to be very well thought of, apart from the weight saving. Some of the American reviewers on the other hand seem to rave about them. I only go out in the summer on the Giro, so winter hardiness is no problem for me.
