    I'm a bit of a tubular snob, and even I'd say that's overthinking it.
    The width between those two tyres in similarly marked sizes will be small enough that I certainly wouldn't worry about it.
    Width becomes a meaningful issues when we are talking about say... my Hed3 with a the choice of a 19mm track tubular or a 23mm road tubular... THAT is a meaningful difference for aerodynamics on a wheel which depends on narrow tyres to be quite fast.

    End of the day, they are both race tyres. Both will wear quickly - the rear much more quickly than the front. Both grip well, both are decent choices.

    Glue them up, worry less :-)

    this.

    if youre going to over-think or stress about something, make it the gluing process.

    veloflex extreme is easily the best tubular
    but they don't last long about 2300km for the rear

    No, they aren't.

    Unless by "they don't last long" you mean half of them fall apart.

    unless "throwing more dosh at tyres than the next fella for no real-world gain" equates with "easily the best"... incorrect

    fyi, had a long conversation with folks at HED a while back. they believe that until really high yaw angles a 19, 21, or 23 will not make any effective difference in aerodynamics on the H3.

    if you ride outdoors, it's really a non-issue.

    if one is riding the track indoors where there might truly be a 0 yaw situation, then it might matter a bit more.

    i'm pretty concerned with all these things but even riding at 25-30mph on "low wind" days one rarely truly (if ever) sees "no wind".

    you can decide if you care about this info, but HED do not.

    to the OP: one of the biggest differences between the tires cited is the inner tube. contis have butyl tubes for all (unless you get the ones made for the world tour teams); vittorias use latex tubes, at least for the high-end versions.

    well, my H3 is a track-specific wheel for me this year...
    If I get my ducks all lined up, I'll shoot you a PM about this - I've got questions.
