I fitted T Trac2's last year and they were a very reasonable price so I am sorry to hear they have been discontinued as I wont be able to get a replacement if I have a blowout and the Sprint Classics were twice the price.
The alternative to Vredestein's and Continentals last year was I think Hankook which are more of a premium brand that they used to be. No experience of them though.
