Trout usually like a faster retrieve...Brown trout usually like it ripped with very short pauses. They seem to shy away from a jerkbait if the pause is too long. If they are inactive and you can position your cast right, a long upstream cast a slower retrieve with small twitches every couple of seconds. Browns are pig dog ambush predators and they eat the front hook 95% of the time. Rainbows are curious, and they like to chase, but they seem to be passive mid-water grazers for the most part. No pauses to keep em chasing. They usually take the tail hook most of the time, especially on the bigger baits.
Have not tried a wart on them, but I dont see why it wouldnt work. Moved some warts and blade baits to my trout kit this winter. Figure they might work well in some of the deeper spots were its hard to get a bass sized 1/8oz hair jig to the bottom in a timely manner...A couple spots on the Eleven Point & NFoW come to mind.
