Ok I need to change from my stock tires (noticed sidewall cracks in both front and rear and some cuts). My LBS recommended the Bontrager AW3 Hard Case (not sure if they are the full hard case or the Hard Case light). Any opinions on those or the Gatorskins. I have the Specialized Esprion Elite Tires and like those but was looking for something faster and tougher. I know "another tire question".
