Track racing bike-build

Went in to Condor earlier to have a look at the Cervelo T1 and their new Lavarro framesets, guy says the Cervelo costs twice as much but the Condor is better as the welds are better but the Cervelo is more aero as it's been in the wind-tunnel, then proceeds to tell me that the change in frame shape on the Lavarro is for added comfort which makes it better.

Really struggling with choosing a frame for next year.

Thoughts?

Here are the contenders so far:

None of them.

Just use what you've got, it won't make any difference. Unless your current bike is super shite.

Really though, it depends on your price point and aims, there's slightly more choice for endurance based frames and less choice for taller sprinters who don't like the tall headtube on many of the modern frames in the larger sizes (Like that T1)
