Who had the fastest hands?

[Bookkeeper]

roy jones
shane mosley
meldrick taylor
floyd mayweather
hector camacho sr
zab judah
sugar ray leonard
Ali

I would give the edge to roy. plus he had it at higher weights and carried it to each of the weight classes he moved up to.

Your list matches mine perfectly except I would not give the advantage to Roy. It would have to be between Meldric Taylor and Shane Mosley, both of those fighters moved like the flash, they were both faster than Jones but remember they were also alot smaller. You could add Terry Norris on the list also
