we started using tadpole #2 the last two seasons and they have worked great with our worm harnesses.The #2 cost about $6 a piece and weigh 1.3oz I think.They don't seam to pull to hard and is easier to read inline boards.When a fish bites the weight tilts and fish comes up easier.The problem with #2 is they bottom out about 27 ft deep.The #3 tadpoles are about $15 a piece and weigh 3oz if need to fish deeper.I don't have any #3 yet,ive just use our old 3oz inline from before.With crankbaites,it is not recommended to use a planer to get lure down like a tadpole or dipsey.You could use the tadpole for spoons with no problem though.
