Gaspari always was contest ready 1-2 weeks out and he never used diuretics.
How in the hell do you know Gaspari
never used diuretics? Come on now.

Centopani isn't known to be one those extremely conditioned atheletes. Well he IS extremely lean
but we're talking about those last couple of percentages when compared to a few of the others.
It may be somewhat due to genetics because some just don't manage to get as sliced - look at Kucklo who was mentioned before. Kucklo and Centopani have used the same gurus many others so you have to think it has a lot to do with genetics. For someone like Kucklo to get really sliced he might have to drop 40lbs of mostly muscle so it's not worth it. I don't think it's just laziness.
