I used 23mm Krylions during my traning rides on clean streets. They were awesome. Then I became a commuter and started riding dirt-infested streets, and the awesomeness had gone.

So I swapped to 23mm Gatroskins and the awesomeness had come back. Well, at least the punctures disappeared. Gatorskins are a pita to install. The funny thing is, one day it could take me 45 (forty-five) minutes to change one tire, and the next time it would take me 18 (eighteen) minutes to replace both tires (like the other day I went into a pothole and blew both of them).

Gatorskins are also a lot harsher riding the krylions, a LOT harsher riding. Grip isn't as confidence inspiring either because 1. the compound is softer and 2. I haven't reached limit of grip yet coz I dont feel cnofident enough with grip levels on these guys.
