I fished against Fishhead (Joe) and Beetlespin (Lance) for several years in MSBM and have a great deal of respect for their skills and consider them both to be top notch anglers. Fishing with Lance is what finally pushed me over the edge and power fish a little more than I used to. Another friend I consider to be very good is Joe Pickett, who spent a lot of time helping me become a better fisherman and boater and is very versatile on the water.
I guess I am also a little partial but have always considered my Dad to be very good. He rarely ever fishes a tournament anymore, but when I was a kid he had the skills to catch whatever type of fish he wanted from bluegill to catfish to crappie to bass.
I have always been a believer that time on the water = better fisherman. Just like other sports it seems some people do not have to practice as much as others.
I think what you may need to ask is who is the best fisherman at specific techniques...dropshot, texas-rig, carolina rig, crankbait, spinnerbait, jig, spoon, topwater, senko, river, lake, etc...
