Thank you for reporting back on the Efficiencies. This is great to hear. I got the sense from Schwalbe CS that the Efficiency was a "new and improved" version of the Supreme. The Supreme was poor off-road if the dirt/gravel was wet..the Efficiency seems to address that somewhat..for what it is (a road tire rather than primarily an off-road tire).
Good news..thanks!
