Personally I am big fun of the open tubular type construction that Vittoria, Veloflex and Challenge use. They make for a very supple and fast tyre that is also very comfy. For fast winter and autumn riding I use the Vittoris Open Paves and for spring and summer so far this year I’ve used the Vittoria Corsa CX, which is really lovely but it doesn’t like the wet much at all.
The Open Tubular construction though, while very supple, does kill longevity. You’ll get maybe three thousand KM from a set though they are not any more expensive than vulcanised types from Conti etc.
I’ve got a set of Conti 4 Seasons on the winter/commute bike and I seem to be getting a puncture once a month on those currently which is frustrating. That equates to about 600kms.
