I'd agree with Greasy B. There aren't many, your odds are low. Rainbows, even big ones, don't take a jerkbait well IMO. Back hook takes mostly. They like smaller offerings. Pat's rubber legs, egg patterns, marabou jigs, and anything with peacock herl takes rainbows when prospecting. If sight fishing, toss a jig, egg & dropper. On the White I 'd go with a scud, sow bug, or soft hackle fly behiind something I can see.
