Probably my biggest pet peeve about professional fishing ? The amount of info shared or obtained before the off-limits goes into effect. It's always happened, and likely always will. Had a friend who was just down on Cherokee and he said most of the Elite guys he saw practicing before the off-limits period had one or two locals in the boat with them. These guys get lots of information beforehand. They're still some of the best in the world, but they get a lot more help in various forms than people realize. It's why at present, MLF is the only true game in town, IMHO.

Some are probably just scouting early, but many FLW guys are probably there for the Open. If you look at the official roster when posted, you'll see a bunch of FLW pros. Some simply have nothing better to do, but most are either trying for an Elite Series bid or a B/M Classic invite with a win.
