No doubt I would fish with my Grandpa. He always dropped what he was doing to take me fishing. I'd love to have a 100 fish day with him in my boat. I can still hear him yelling "oh ho ho I got one!!". He sounded like Santa Claus setting the hook!
Others would be Hank Parker and Shaw Grigsby.
Oh, and of course Steve "Big O" Parks on Lake Falcon, Choke Canyon, or Amistad.
