well, I am no expert on toledo bend... but i would have some idea's for you.
1) the time frame your talking about is prime time for pre / spawn on toledo bend. For me it's a very successful time to long line troll weed beds in 14-22 ft of water with 1/16 oz jigs. (or if you have a spider rig setup that will work great)
2) depending on weather some fish may be actively in spawn mode by that time... in which case you can catch in 2-6 ft of water with jigs
3) if any in your party are retired military, and your looking at the southern end of T/B... i can certainly recommend the army rec site there... they have many nice new log cabins and yurts for rent at very inexpensive rates.
Other than the above i hope someone else can chime in with some more info for you.
If you end up coming down in march shoot me a pm on here, I am tracking to be free most of that month and have been planning on regular toledo bend sac trips anyway... would be happy to show you around.
