best tubular track rims

[gogo419]

Looking to build up a new set of track wheels for training and racing. Not looking for a carbon fibre rim but a good quality tubular aluminium rim instead. Preferably not deep rim either.
I hope people can offer advice and comments on this.

Cheers

My guesses would be Mavic Reflex for relative availability, or Araya 16B for being incredibly lightweight (as far as aluminium goes).
