I have also switched over to the Schwalbe Marathons - and I am shocked at how fast they roll and how durable they are. I got sick of burning through the JBs and tried similar sized Paselas, but they also only lasted for about 1000 mi. The marathons have about 1000 on them now with hardly any noticeable tread wear (and no flats). I ride about 30 mi a day to and from work and the peace of mind is great. I really thought I was making a compromise, trading weight and rolling resistance for durability, but that has not been the case. One caveat - I don't have a lot of hills on my route. They may be slower going uphill, but based on the way they feel every day, I wouldn't hesitate to ride up the mountains around here.
