WADA's Luxembourg branch should obviously pursue a lifetime ban on Schleck for this. He didn't merely ingest a teaspoon of clenbuterol, which causes a rider to win a 3 week bike race by 39 seconds. In that case, an obvious dimwit ingested something he shouldn't have and received the requisite stripping of titles and 6 month slap on the wrist.
No, testing for a masking agent implies that there was more sinister things going on. Who knows what sort of drugs were in his system? And consider that he has had a relationship with the king of doping, Bruyneel, who has a list of violations SO profound and disgusting that decorum prohibits listing them here.
Frank's only escape is if he testifies and provides evidence against his past and present teammates and directors. Frank should have plenty to talk about, considering that his associates, past and present, include guys like Riis and Basso. Cooperation will result in a more lenient punishment, for example, one year, plus, Frank will get to keep all of his minor titles and accomplishments, say, the Luxembourg road and time trial championships.
If Frank grows a pair and testifies against Andy, resulting in Denis Menchov becoming the 2010 Tour de France winner, then no punishment.
Anyone who doesn't agree with this point of view is obviously not serious about cleaning up doping in sports. The current investigation style is like David Millar after he was caught, or like Indiana Jones and the Crystal Skull. Wimpy and Indiana Jones doesn't murder anyone. We need to make it more like David Millar before he was caught, and more like Indiana Jones and the Temple of Doom. Twenty one murders by Indy in that one!
