Swammers are baller for swim jigs as long as you're not in cold water or trying to do a slow retrieve.
My full Swammer review:
-Better as a swim jig trailer than alone, really excellent body shake that makes the skirt move.
-Good marks for durability, can catch many fish on a single bait.
-Poor marks for low speed action, they don't move much or at all if you aren't retrieving at a medium or high speed.
-Poor marks for cold water performance, the colder the water, the faster you have to retrieve to get the tail to move.
Conclusion:
An excellent choice as a durable, summer swim jig trailer.
