They are really solid, last forever and are quite light for a non racing tire. They also have decently low rolling resistance when inflated high.

However, in my experience they are really sketchy in wet conditions. I've wiped out or almost did multiple times on gatorskins. Deflating them in wet conditions works but the rolling resistance is then quite high.

I've found that the Schwalbe Marathons in wider sizes (I think I got 38s?) are much more confidence inspiring and comfortable, and makes up for the fact that I have to change a flat twice a year instead of once a year.

Oh yeah, I've had some extremely solid wipeouts in the wet on mine, but then again I usually just attribute that more to me being a hooligan on the bike more than the tires :P

My Marathons are nice and fast, but slippery on the curves and I'd watch out in the rain
