I had one set that I just replaced with some new ones for a longer trip. Here is my experience:
+ Last a good amount of miles. I had 5,000 miles on both the front and rear and still had tread left.
+ They stick pretty well. I just completed an advanced riders course and had no problems with confidence leaning hard into the turns. The tires held really well. For road riding, I have no concerns taking any corner at any lean angle with these tires.
+ They handle well in the rain.
+ Rode the tires in Wisconsin cold and heat with no problems.
+ Seems to be a good mix between tire stick and long life.
- Not sure if this is fair with 5,000 miles on them, but they got pretty squared off.
- As you lean over more they tend to resist the lean. It might be just me, but this seemed to be more pronounced as the tires wore.
Overall, I have very good confidence with the tires. I need to try the Avons next. From what I have read/researched it is between the Avons and Contis for me. I stuck with the Contis again because I needed to make sure I could go over 4,000 miles in one trip on one set of tires.
