I would say keep a good eye on your top tube lengths. Not so sure about rest of the world, but anything above club racing here is subjected to UCI rules. I started out on a 58cm TT Cinelli and I just couldn't stretch out enough within the parameters of the rules. In the end it was a longer TT or nothing. I had almost settled on going custom aluminium until I heard of the Alien frame development. I prefer sprinting and I had given my Cinelli skid marks within the chainstays from flex. The prospect of a larger stock frame meant most likely more flex from the larger dimensions as they're primarily built as a points racer style of bike, not a sprinter.

If you're not sprint orientated, then I might suggest the Felts as they go up to 607mm TT length. If you like to sprint, then go custom aluminium or look for something carbon like the Alien or even Serenity (60cm TT but for a significantly higher price).

As it is, my fitted sprint setup on the 61cm TT Alien is with the stem 25mm lower and a 20mm longer stem (140mm) than in the pic. It fits like a glove and I have longer legs as opposed to a long torso.
