I fear that LA would treat any more discussion of his doping as an ego trip. Far better to talk to the likes of Di Luca, Sinkewitz etc. Its the mid rank riders and especially team managers with a shady past who could provide the most insight rather than LA who, with his resources and clout, was in a different and much smaller league. All IMHO obv.
ETA; Cookson is off to a good start. I hope he receives support from the likes of Walsh and Kimmage.
