6th Sense Crush Flat 75X
You pretty much hit the nail on the head with those baits you mentioned. Around here, when the water gets cold, I like to draw a reaction bite. And I do that with this crankbait. It's flat so it has that tight wiggle that's so good in the Winter. It comes with good hooks and quality components, not to mention the colors are freaking awesome! Megabass Drunk Fly
Another good bait that I like is this little jig in a black or black/red color. This little guy is very good at enticing bites in cold water because of it's unique, compact size. It's a weird looking bait but I catch A LOT of fish on this bait in cold water, and throughout the year. The head design is my favorite part about this little guy because it makes the jig stand up and perform a defensive craw position. It's a great little tool to have in your arsenal for cold water.
The best advice I can give you is to fish SLOOOOWWW or create a reaction bite. Points and creek channel swings are your friend at the moment as well. Any place where the channel swings up against the bank and there's shallow water close by, is good for cranking and slow rolling a spinnerbait. Don't forget to throw a jerkbait around bluff walls!
Hope this helps you and tight lines.
