I like these too, definitely grippier than the gatorskins I have on my other bikeSCHWALBE MARATHON PLUS.
People really need to use these tyres.
I've done over 600 miles on them in the past two weeks and not one puncture. Very grippy, low rolling resistance.
According to a lot of tourers I've spoken to and numerous reviews on cycling forums, they last for thousands of miles and are almost unpuncturable - you can stick a drawing pin in the middle and it won't penetrate.
Amazing tyres.
