I used to do some national races but nothing big, was lucky enough to have a good cycling club nearby.
I think you are probably right that the pro world is more cynical of the LA story, but even then it is still diverse, the LA physiology for me was around before the managed narrative as some would like to say, as I was always interested in the science aspect going back to Greg LeMond days, with his own application of its use that was pretty innovative in its day - also exceptional body like Hinault, Indurain, and LA.
However I must admit I am more cynical of Alberto Contador myself, he has made it look even easier than LA and also had his name indirectly (not enough proof) linked back to the Spain drug busts, I do hope he has allowed researchers to also allow a study of his performance like the names I mentioned.
Also what became lost in the AC case was that the UCI actually tested beef from the butcher where the steak came from and could not find any traces of the drug in their purchased beef, nor other beef they tested from the region.
So while the amount was small in AC's blood stream, the defense that it must had been used by the farmers is tough to accept.
The only evidence personally I will take for LA being guilty is that primarily from Hincapie, and possibly also Levi Leipheimer, due to the fact LA has not failed the WADA credited lab controlled drug tests.
Hincapie as his closest support rider I think would have an inkling, so why it will be interesting if there is any truth that Hincapie will be a witness - which I am still open minded on this latest news considering the previous misinformation relating to what he said.
I do find the conspiracy hard to accept that somehow LA manages to pass the tests while certain former team mates failed, so he somehow used techniques beyond what could be tested; and yet those who have been caught and accuse LA showing them how to dope did not use the same technique, quite incredible IMO.
However again this does not mean LA is innocent, just that some of the claims by those caught seem dubious.
All comes back to Hincapie, who I would say most would listen to and accept as a credible person.
