I run Dunlop Qualifier GP Racer Medium compounds on the road. Prior to that the qualifiers 2's; and I love them. During the summer I got caught out on a ride when the heavens opened, and an inch of rain fell in less about 15 mins. I was 30 miles from home, and getting really soaked in summer gear, so I opened the pig up and went for it. Got home, and after drying off, the realisation dawned on me that I hadn't made any allowance for the wet roads. Those tyres stuck like glue, even in torrential rain. I even had my knee down in places, and for the most part I was on a mission to get to somewhere dry. The only way I am changing from Dunlops is if they stop making the GP Racers.
Tried 2CT's about 5 years ago on the recommendation of a friend and hated them; took them off after I nearly high sided on a corner I regularly ride. Like Pirelli's but will always take the GP racers given the choice, they just suit my riding style perfectly.
