I hate to beat the dead horse anymore but I have to!!! Yes, its about Schwalbe Marathon tires, what else right?

Those of you running Marathon XR's - how is the rolling resistance on these bad boys? I know they'll last a long time but am not sure I want to compromise these for the occasional dirt ride I'll be doing with my bike (using XR's if I got them) compared to the Supremes (what I'll get if I don't get XR's). I'm just hoping I can use these tires for two purposes.

If I get Supremes I'll only use this tire set for touring and have separate sets for road riding and probably a cyclocross set too (a bit much if you ask me).

I will be using these for mostly (95%) paved touring and the occasional dirt ride (fire roads/singletrack).

Here is a picture of the two different treades (although I don't know how worn these tires are); http://www.flickr.com/photos/eddoklo...an/3551471562/



Sorry again for a beaten topic, really!!
