I started riding Schwable Stelvios about in April They are nice so far - ride much more like a Vittorio Rubino but seem to have the durability of an Armadillo. I rode Armadillos for a long time and they certainly were great as far as no flats ever and took a lot before the red layer started showing and then before threads started to show. However, they ride like tanks and you really feel everything. I found them sluggish if they weren't pumped up to 120psi and a little to tacky/sticky after they got wet. My two month experiment with Rubinos was a disaster. I must have received two tires from a bad batch. I got slits in my sidewalls and on the tread. Something pierced my tire and went through the tube in two spots (though close enough that only one patch was needed). I did not skid a ton on the Rubinos but used to on the Armadillos and have continued to on the Schwables.
