What weight class produces some great technical boxers?

The lightweight division has produced the most technically sound fighters in history IMO.

Gans... Leonard... Duran... Whitaker... Williams, and that's just scratching the surface.

I think most of the weight classes produce their share of so-called technical and smart boxers. The flyweights have seen the likes of Pone Kingpetch, Ricardo Lopez and Ivan Calderon. The bantamweights have had the likes of Eder Jofre, Lionel Rose and currently Anselmo Moreno. The featherweights have had the likes Willie Pep, Salvador Sanchez and now Yuri Gamboa. The lightweights have had the likes of Benny Leonard, Tony Canzoneri, Pernell Whitaker and Floyd Mayweather. The welterweights have had Sugar Ray Robinson, Kid Gavilan, Oscar de la Hoya, Whitaker and Mayweather, Jr. The middleweights have had Robinson, Roy Jones, James Toney, Bernard Hopkins and now Sergio Martinez. The light heavyweights have had Maxie Rosinbloom, Tommy Loughran, Billy Conn, Michael Spinks and Jones Jr. The cruisers have had Carlos de Leon, Evander Holyfield, David Haye and now Yuan Pablo Hernandez. And the heavies have had Jack Johnson, Floyd Patterson, Muhammad Ali, Larry Holmes, Lennox Lewis and Riddick Bowe and now the K Brothers.

If your asking what division p4p has produced the best technical boxers, its Welterweight& its not

even close, from 'Sugar' Ray Robinson to Leonard to De La Hoya to Mayweather even Trinadad was technicaly very good.........
