Just got back from a 13 mile ride, my first ride with the new Hutchinson Python Light USTs. Now, let me preface this review with the fact that I'm no expert. I've been riding for nearly three years now and this is only my third set of tires. I went from Hutch scorpions which were a joke, to Panaracer Fire Pros 2.1, which kicked major ass, but were draggy as Hell. Anyway, I was very sceptical about the Pythons, especially since I had such a bad experience with the Scorpions. But, after riding them (gingerly a first), I have to say they weren't that much less forgiving than the Panaracers. Maybe it's the fact they were UST, which supposedly means better traction. What I did notice was the weight savings. These babies were L I G H T by comparison, and they felt much faster. I ride in southern California, so from what I read, Pythons were designed my riding conditions. Anyway, they did better than I thought, and the benefits of lighter, faster tires were fantastic! Just thought I'd share. By the way, I'm 185 lbs. and rode 32psi front, 35psi rear, felt about right.
