Put it this way, which secondary flaps (im talking about the little flaps mounted the to FW endplates) looks like the worst design on the front wings of the following teams:
Renault
BMW Sauber
Williams Coswaorth
Midland F1
Toyata
Quite easily Toyota, their car seems aerodynamically very poor, especially for a team with such a huge budget, such an advanced wind-tunnel and especially considering that a second wind-tunnel is on the way.
I have been very suprised by the aero package on the TF106, and I really believe even Midland have a cleaner package...maybe even Super Aguri. I think that they rely too much on a good engine to make up for their aerodynamic defficiency on the straights.
