Actually the Brownlee's never use clip-ons. The bike leg in the ITU format is basically a bunch road race.
Agreed on the Air or Propel being good options. Propel Advanced is phenomenal value this year, and the Adv Pro 2 is only £300 more than the S2 with 50mm wheels included. S2/S3 is a brilliant frame though.
