From that list it's between Jose Napoles and Luis Manuel Rodriguez for me. Kid Gavilan is also my favorite Cuban fighter next to Napoles.
Although some brilliant fighters here, I suppose my favorite would be Luis Rodriguez. I just loved his style and his willingness to entertain the audience. His jab and overhand right were incredible weapons but I loved his inside work. He wasn't a body puncher in the sense of a Zarate, who could fold you over with one punch, but a steady body puncher who could bang the body for 15 rounds. Also I loved the way he took on the middleweights and handled fighters like Briscoe and Carter. Both monsters at middle. And I do go on record as scoring all 4 of his fights with Griffith in his favor.
