I'm looking to get new tires - the Michelin Pro 2 Race I now use have worn out after about 1300-1400 miles (at least the rear, anyway...). I'm looking at probikekit.com, and the Vittoria Rubino Pro seems a comperable tire for less money. I was set to buy them when I noticed there were two versions - Vittoria Rubino Pro vs. Vittoria Rubino Pro "slick".

Any reason I should pick one over the other, and are they as good a tire as the Michelin Pro 2 Race?
