In My opinion we can go fast on any tire made. All of the brands are very good and once you set up your bike and learn the characteristics of the tire you can succeed on any of them. That being said tire choice should be determined on several factors. How the tire works for you and you confidence in the tire, customer service, price and contingency might be a few. If one brand was all things for everyone they would not have any competition. Decide on what is important to you and go fast!!

I posted the Continental prices in the vendor forum but a 120/180 DOT set is $365 and a 190 set is $382
