The Pakula Paua Cockroach Semi Soft is a proven lure that works well in any trolling position.  However, most anglers prefer to use the Cockroach as a short rigger lure.  You'll find that the cupped head shape sticks to the water nicely as you troll, splashing as it hits your wake and maintaining a tight wobble as it glides through the water.  You can troll the cockroach at a wide range of speeds.  This lure is a semi soft head, so it's not a hard resin like most trolling lures.  Made in Australia.
