With regards to the honesty of Team SKY, in the Sunday Times there was an article by the journalist David Walsh (I think that's his name) where he has been offered full access by Brailsford. They're booking him rooms in the hotels, he's travelling in the bus, access all areas. The only rule "don't piss off the riders".
Unfortunately due to the Times' pay restrictions I cannot post it.
Fair play to Brailsford for being so open and ultimately good for the sport. Not so good for Team Sky as if there's no drugs then the journalist will find another angle to create a story.
