Call me crazy but I have never fished a roostertail. I just thought they would not catch bass. Anyway forgive me but how do you fish it? I may have to add one to the tackle box, if nothing less its an excuse to go to the outdoor stores.
JMHO
I don't fish with them for bass much as I think there are better baits, but they will catch bass. Pressured bass don't seem to be fooled by them. They aren't a finesse bait and they aren't for lethargic fish. They cover a lot of water, so if the fish are active you can put it in front of a lot of fish's face.
As far as how to fish them... I use them mostly for trout, however the methods are much the same. In a pond, I like to cast perpendicular to the shore. Depending on water depth, I'll count anywhere from 1-10 seconds to give the roostertail a while to sink and then I'll start cranking. Usually a steady retrieve works best, speed varies, but usually on the fast end. Bass sometimes like when you pause and twitch them to throw some erratic action into them. My buddy swears by them for catching small river walleye. Something he did he could get walleye, usually in the 8"-12" range to just hammer his. I could never duplicate it.
