As far as I'm concerned the Conti GP 4 Seasons is my summer commuter tire. Have it on both my road bike and cyclocross/lht rig that get over 90% of my summer miles. Subtle, good handling, good puncture resistance are the reasons I like them. Ok wear resistance, and spotty QC keep me wondering if there isn't something better. I have had a couple where the Vectran had delaminated on the sidewalls.
