PRM,

When all else fails I like to use a black woolly bugger with about 4-6 strands of flash added to the tail and then twisted and wound up the body between the chenille wraps to the hook eye. Has worked on just about anything I've fished for including warm water fishies. Caught a nice "bugle mouth bass" once while bouncing one on the bottom. It's what my mother-in-law called a sucker or carp.
