Good points 5bites. I'm not against them spots at all but I would like to see what the results would be. It might just be that some people are able to keep a few fish because they aren't able to catch and 15 inchers. Or maybe they take those spots instead of the fish that have the potential to grow bigger. I think you leave Table Rock as is though and only do this on Stockton for a trial.
And while I agree that I would rather catch a 4lb spot over a 4 lb largemouth, I also realize that my chances of catching a 4 lb largemouth are much, much greater than catching a 4 lb spot. I'm not convinced though that a largemouth is going to take the place of a spot though. They seem to live a little differently.
Texas may not be "getting it done" but it's a hell of a lot better there than it is here. But many things factor into that, not just species of fish.
Some of the most fun you can have in the summer is floating down the James river catching spots. You find one and you usually find a bunch. Easy to catch and a heck of a lot of fun.
