Nice; those Diamante ProLights roll really well for a cheap tyre. My brother and his wife have just upgraded to them on their track bikes. Of course, 36 spokes flailing away in the breeze are going to kill any speed you've gained with the tyres...
Luckily have CX Rays on my Cane Creek Volos tubs with (according to WW sources) the best buy Schwalbe Milano tubs.
edit by strange coincidence I was just looking at the Vittoria Japan website and saw those Ultra Speeds listed as their "Track clincher" tyre. Never herd of them before but S-Deals seem to have some 23c.
