great post Gregory - and i concur with your analysis of the excellent back and forth at this forum. while i tend to agree with pmcg76, ludwig and blackcat do paint a scary and plausible picture. call me naive, but i would prefer to believe that some riders are doing it "clean" (whatever that means) and i will continue to root for those who i think are riding on bread and water. (thats half the fun anyway ) if i was convinced it was all dirty, i dont think i would bother.
