I guess the consensus is that the anti-doping movement has moved on significantly in recent years, but we've had many false dawns before (remember the '68 Tour of Health?) and we can't afford to be complacent or consider the battle against doping to be anywhere near 'won'.
JtM - Yes, the image thing that Rock have going on does make them quite an appealing package, superficially at least. Plus, Hamilton is from the Millar era (if there is such a thing). I do think that the post 2006 dopers will get a much rockier ride when they try to come back.
