Man I use to fish those things and a similar one called a lazy Ike.Caught a lot of fish on them but can't say I ever caught crappie on them...but I never used them to target crappie by using trolling .

The very first bait I ever heard about for trolling for crappie...it was in the late 60's maybe 70 or so (1960's that is) was the hot shot.
