We have had the best luck with Gatorskins. We are a larger team then you and your stoker and typically ride with 28 and 32. We've been using 32's for the last 6 months and think that is our regular tire now. People here are using Conti 4000's/5000's and 4 seasons with good luck. We've stuck with what is giving us the most trouble free performance. The Gatorskins are not know for being the most smooth but we've enjoyed more then a decade of good results.
