All I can tell you is I moved to the Shoals area almost 3 years ago, and I've had one day where I might have caught 15-20 keepers. Every other time I've gone has been a complete bust. I recently upgraded (or downgraded?) from my kayak to a bigger boat so I could get more places, but it hasn't helped. I'd love to know if anybody ever catches any over here.
I fished Wilson, a little farther downstream than you're talking about, for probably 5 hours yesterday will nothing to show for it, except a handful of small bass and some nice weather. I know there are crappie over here somewhere, but I've yet to find them. I admit I haven't gotten to fish a whole lot since we moved, but man, the times I have gone have been humbling. I'm thinking about heading over to wheeler soon just to see if I can regain a little dignity.
