Cold fronts and beds.. tough fishing.. BUT you can catch 'em still

Get yourself some spider jigs (the ones that have a tube body with arms on the front, and some 8 - 10" swim baits. I cast up on the bank if I can, and slowly work the lure into the water and when it gets on the bed kill it...Just let it lay there for up to 2 or 3 minutes.
Another good way is to use a drop **** rig with a weighed soft plastic jerkbait and a 1/2 ounce sinker on the bottom. Cast out a good ways past the bed, then slowly drag it along until you get close. Then kill the jerkbait into the bed. If you use a LIGHT weight on the jerkbait, you can lift and lower it in the bed, without moving the heavier drop shot weight. I've done this for up to 15 minutes before the bass finally took.
That a really good deal on that megastrike. I just ordered 5 more tubes - I originally bought 7 or 8 about5 years ago from dick's sporting goods and it was around $15 atube.
