Jack Brown Greens have become my favorite tire. On my commute home, I can loop out and pick up some singletrack, which is typical mid-Cal trail conditions with smooth dirt with bumps and fist sized rocks embedded in the surface. Plus, they've done very well on the network of fire roads, which are semi-graded dirt surfaces. Before those existed, I was pretty happy with 32 mm Paselas. If I need a little gription, I'll run a 35 mm cross (treaded for cyclocross) tire. They all end up with a fair bit of deflection when I press my thumb directly in from the tread (not pinching the sidewalls). However, I'd say that if you are "bouncing around", you might want to experiment a little bit with pressures. That's usually an indicator that the pressure you are running is not letting the suspension (tires) do its thing. I'm not sure what the size of the GB tires is (RT's are 28's, right?). Running 28 mm tires a bit softer tended to generate a fair number of pinch flats for me. For my riding style, size and conditions, 32 - 35 seems to be a good place. hope that helps, - Jim -- Jim Edgar cyclofi...@earthlink.net Three T-shirts Now Available: "I've Got Downtube Shifters..."
