I have thought about this over the past couple of days and have come up with the following.
Favourite Pro Tour kit = Francaise des Jeux, because its simple, clean and provides a neutral easy to spot jersey.
Worst Pro Tour kit = Liquigas, now there are a few contenders here including AG2r and Milram (looking like a cow on a bike is just wrong) but I go for Liquigas as the lime green is just too harsh for me to look at any point in time.
Favourite Pro Continental/Continental kit = Cervelo Test Team in that again like the Francaise des Jeux kit its simple and elegant, plus as seen last year interchangable colours with the seasons.
Least favourite Pro Conti/Conti kit = Due to the numbers this was a really tough one to pick but overwhelmingly and considering (if i remember correctly) that they have lost their Pro Tour status it is Footon-Servetto look a little better in the peloton, somehow! However, it still looks like someone has stood in a pile of vomit with a muddy foot, and i'm afraid that is just completely off the scale in bad kit design.
