The more I think about it, I'm with skippy (Phill Anderson). Lance was the best of the pack in the era of doping.
I can understand in what he did, other teams where doping and he was getting his Ass whipped. So he did what he could do to make it a level playing field. I guess it's like me and my 30 year old steel racing bike, it's mass is 11 kg. Now if I want the same advantage when going up hill as my friends who ride 6-8 kg machines, I would have to get a lighter bike or deal with the energy expenditure of carrying an extra 5 full water bottles up hill ~ (4kg). Carrying that extra mass over a number of climbs will certainly take its toll.
Now I don't condone his bullying of others to keep his secret. That's bad form.
Being a Cancer surviver myself, I like what he has done with his live-strong company, and his fight against cancer.
