In late winter, just before largemouth get active for pre-spawn a great technique is to finesse them with a drop shot. This works especially well in frontal conditions. Since you're dealing with potentially huge fish, you'll want a pretty heavy finesse set up. I like 10lb braided seaguar 832 main line with a 10lb seaguar invisx leader. The owner covershot hook is perfect for this technique tipped with your favorite straight tail work, I prefer the zoom trick worm. The trick is to find thick isolated clumps of hydrilla on your side imaging and target those with accurate casts. You may loose a few because of the light set up, but you'll also get bit when nothing else will work.
