I'm eying purchasing a Brooks but am not sure whether for good roads it makes sense getting a saddle with springs. Price is not an issue, I'm buying it for many years to come so the difference is irrelevant. Nor is the extra weight.
So the only question left is whether the springs are useful for road touring. I don't know how 'springy' they are, i.e. whether the springs are hard and thus smooth serious bumps or they are more for lighter vibrations.
